I did some searching and could not find a website that lists US mint historical prices on proof sets, uncirculated sets, ASE's, gold, platinum, etc... Does anyone know of such a site or reference? Examples: What price did the US mint sell a 1998 1/10 oz unc. platnum coin for? What price did the US mint sell a 1995 Silver Proof set for? Just to clarify, I don't want anyone to answer the 2 questions above, I'm just wondering if there is a website that has all of the historical pricing data for mint products.
All of the original issue prices of the Proof and Mint sets are listed in the Red Book. Not sure where you can get the info on the bullion coins, I'm pretty sure they are not in the Red Book though.
Issue prices for modern commems can be found in Coin Market, the monthly price guide published by Numismatic News. Issue prices for all bullion coins can be determined by simply checking the historical price of the issue metal at the time of issue and adding a small percentage, say 10%. But a web site with all of this - none exist that I am aware of.
