Finally won another gold coin auction, after taking a break of almost 3 months. This one is a 2006-s San Francisco Old Mint MS 70 coin... http://www.ebay.com/itm/2006-S-5-Gold-Coin-San-Francisco-Old-Mint-NGC-MS-70-Auction-1-/361670816777?ul_noapp=true&nma=true&si=wkUe26vOh3ixo8hBtwmqbU%2Bg8s8%3D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557 Looking at recent prices of this coin, it appears to be one of the more unpopular coins of the $5 gold commemorative series, having a premium of 10.5% above spot, even in MS 70 condition. Despite its unpopularity, though, I see mostly good points for the coin: 1) With a low premium (10.5%) and fairly low mintage (17,500), there is very little downside for this coin. 2) In my own collection, having both the original 1906-s Liberty coin and the newer 2006-s commemorative coin (with Liberty reverse) is a good match. I will be able to see how well the Mint replicated the design for the reverse. 3) Graded MS 70 in a sturdy NGC holder. After considering the cost of buying a raw coin from the Mint and sending it in for grading--not to mention the possibility of receiving a flawed coin from the Mint--only now have I fully realized the advantages of having a graded, slabbed coin included in the purchase price. This coin was sold by the dealer along with two other coins like it. The buyers of those two coins paid 5 dollars less than I did. When the same dealer returned the next day to sell two 1997-w FDR coins, I returned the favor (to one of the buyers who kicked me out of the lower price range) by bumping his bid on the two coins from 380 to 430 on one coin, and 406 to 430 on the other one (using bids of 425), resulting in that buyer paying 74 dollars more for both coins (as compared to me paying 5 dollars more for my 2006-s coin). Revenge is sweet!
