I am disturbed that all the posts and valuable threads are going to be trashed.
Granted, there was some trash that needed to be taken out.

However, It seems the same vehicles to create arguments and controversy are here already installed... So. I guess time will tell the tale.

Anyway. This took a fair deal of time. Before it is GONE FOREVER.

Hello GIM'ers,

Here is a glossary of Numismatic Terms;

I didn't see one on here and thought it may be helpful, to those of us who buy mostly bullion. Please let me know if there are any incorrect
terms in here and I will delete them.

IN an effort to get this UP,not ALL entries have been proofread and researched as of yet.

edit: 4/8 -- I am blending and adding definitions to be the "most" concise. Please feel free to post additions, modifications, additional definitions and I will gladly add them to the initial post! Thanks!
When finished I am sure that GIM will have the most concise Glossary of Numismatic and Bullion/ PM terms on the web!

edit: I will try to add, the 2 letter grades (whatever is missing) & MS (or Mint state) Scale,
also, additional terms not in the list.

Proof : a special process for producing coins of exceptional quality and brilliance. Proof coins will exhibit a full strike, mirrored surfaces, and sometimes a cameo effect.

A proof coin is made with a specially polished and treated die!
By treating the die in a special way, the coins it produces have a different appearance. Modern technology allows the high points on the coin design to be acid treated (on the die). The background (field) design of the coin die is polished, resulting in a mirror-like look on the coin it strikes. This gives the finished coin a frosted look (frosting) on the raise parts of the design, with a mirror like finish on the background. This contrasting finish is often called "cameo". (See picture above.) On some older coins a cameo appearance is quite rare. The attribute "CAM", when added to a coin's description, means cameo appearance. "DCAM" means deep cameo, and indicates the cameo appearance is strong and easy to observe.

Proof coins are struck twice, or more!

Not only are proofs made using specially treated dies, each coin is struck two or more times by the coin die. By striking it more than once the metal is forced into all the crevices of the die, thereby giving a very fine detail to the image on the coin. This fine detail does not appear on some non-proof coins.

Note that all kennedy proofs are not silver. Proofs are also super thick compared to the normal coins. "Proof" is NOT a grade.

Proof set: the specially packaged set of Proof coins produced and sold by the U.S. Mint each year.

'Not worth a copper' is an American term of 1788, followed by 'not worth a cent' (1820s)." From "Listening to America" by Stuart Berg Flexner (Simon and Schuster, New York, 1982).

Up until 1990, the U.S. Mint used to manually punch the mintmark into each individual coin die. Occasionally, due to human error, a die would get two or more punches of the same mintmark, sometimes in almost the same location, and sometimes at 90 or 180 degree rotations! Although the mint workers usually caught these defective dies before any coins were produced from them, on very occasions a die would strike coins with multiple impressions of the same mintmark letter.

Coin Grading is don on a number scale from one to seventy. Accompanied by a letter grade for further distinguishing the grade.
One is the worst condition with almost nothing left of the original detail. Seventy would be the highest quality.
A coin with no wear and the full detail struck on the coin.

Below are the Letter grades with some examples of possible number / letter grade combinations & their meanings

PO: Poor - 1
PO-1: A coin with all the detail worn away as long as it has a date that can be identified and enough detail to figure out what type it is would grade the worst.

FR: Fair - 2
FR-2: A coin that meets the description of PO-1 but has some details showing.

AG: About Good - 3
AG-3: A coin that has its rim and readable letters, although pretty worn down

G: Good - 4-6 Common gradients are 4 and 6.
G-6: A coin that has slightly warn rim, details although worn flat, and peripheral letters almost full will grade out as G-4. If the coin has full peripheral letters the coin will grade as G-6

VG: Very Good - 7-10; common gradients are 8 and 10.
VG-8: A coin that has its design worn but still has minor details remaining qualifies
VG-10: Slightly more detail than VG -8

F: Fine - 11-19; common numerical gradients are 12 and 15.
F-12: When the letters are still sharp in detail and there is still detail in the coin but in the low areas on the coin.
F-15: if there is a little more detail in the low lying areas of the coin PCGS will give this grade

VF: Very Fine - 20-39; common numerical gradients are 20, 30, 35.
VF-20: When all the letters are sharp and all there and there is some definition of detail in the coin and not just the low areas
VF-25: Again, If there is slightly more detail the coin
VF-30: If there is almost full detail in the flat areas
VF-35: when the coin has full detail but the high points are worn flat.

EF: Extremely Fine - (XF or EF) 40-49; common numerical gradients are 40 and 45.
EF-40: when most of the detail on the coin is full and most of the high points are only partially flat.
EF-45: is the same except only a few of the high point are flat.

AU: About Uncirculated - 50-59; common numerical gradients are 50, 53, 55, and 58.
AU-50: defined as a coin that has only minor flatness on the high points of the coin and friction over most of the coins surface.
AU-53: is the same but with friction only on half of the coin and a little less flatness.
AU-55: is friction on less than half of the coins surface and very slight flatness.
AU-58: is only slight friction in the high points of the coin. There must also be full detail on the
coin to be graded as any state of AU.

MS: Mint State - 60-70
MS-60: a coin that has no wear what so ever, with many heavy marks or hairline scratches and it might not be fully struck with hall the detail.
MS-61: is the same but with a few less scratches.
MS-62: is slightly less marks on the coin then MS-61.
MS-63: is a moderate number of marks on a moderate size.
MS-64: is few marks or a couple of severe ones, with an average strike.
MS-70: is the highest grade a coin can get, only a few every year ever get this grade. In order to get this grade the coin must have gotten the full strike of the coin and must be in the same condition that it was struck in. it must have no wear or contact marks anywhere on the coin.

Cast: (100 oz. 10/oz Bar): Most of the NEWER 100 oz. JM bars are cast they look like they have been just POURED into a MOLD. Many of the smaller 10 bars that look like a loaf of bread are cast too. Englehard has them too.

Die struck: (100oz / 10oz Bar): This was done about 30 years ago for the 100 oz. bars. They have a ridge around them and sometimes come in a box. The old US ASSAY 100 oz. bars, the AMARK bars, Royal Canadian Mint, and JM Bars what I have seen.

The biggest thing to keep in mind is that 99% of my 10 oz. bars are DIE STRUCK. And they came from probably 20 different makers.

Extruded: (100oz / 10oz Bar): Englehard made a number of these in 100 oz. a few years back. They sometimes come in a plastic see-through American flag box so you can see them on Ebay. They look like die struck but with not the shine nor the ridges arround the product. They might make 10 ounce bars this way - I do NOT know. Here's an article about the process: http://custom.nwtmint.com/process_extruding.php

Go to EBAY and do a search of "100 OZ OUNCE" bars and you can see the differences posted above. Search for a "BOX" too. Once you see the picture you'll get the idea; you may have a few yourself.

Best to YOU all,

PS when I trade I will do the CAST first, Extruded second, and the Die Cast third. Remember if you trade over 10 or more 100 oz. bars they have to file a GOVY report - same GOVY report FOR a whole BAG of $1,000 junk USA real silver coins, OKAY?

This thread really should be a sticky - If at least so that all Noob silver/gold investors, can learn some terminology.

So Can a MOD do so please? Thanks.

Funny how years later I find myself using this as my choice numismatic glossary.

Thanks for the time spent agro. I have referred to it twice this week when buying my first graded numismatic coin.
I also vote for sticky, or better yet, include this in a reference area.

Wow! This still exists!

I would like to note if a MOD could add to "BU" Brilliant Uncirculated - This IS NOT A GRADE, it is a sales term used to say "the coins are new" It means NOTHING in terms of Numismatic value or recognition. The same as GEM uncirculated. Rubbish.

We need to add the derogatory slang that the dealers and collectors use too. BU = "Been Used", PCGS = Pigs, Clad = Crap Layered And Dented, etc. (if I remember more I'll add them to this thread).

Your statement is a 'Slider' uncirc. :rotf:

In the U.S. grading ranges mostly from AG "About Good" to MS "Mint State (Poor, Fair, Good, VG, F,VF,EF,AU,MS).

In Foreign it's a lot simpler with F "Fine, VF "Very Fine", EF "Extra Fine", and UNC (Uncirculated).

Now to confuse everyone here Foreign coins grade tougher so that an EF in the U.S. is more like a VF in Foreign.
They don't have an AU (About Uncirculated) in their grading ao an AU is really an EF as in EXTREMELY-Fine..... a true EF with luster and all the detail.

U.S. coinage is pricey for the older stuff and market driven. I remember when the category AU-58 was created. It's the true 'Slider' and is good to collect for the novice but it also make a lot of money in the Slabbed PCGS Arena.
