USA price history lookup service

Over the years, I have acquired a small library of assorted secondhand price guides and reference books that list the prices for USA coins in various grades: Red Books, Blue Books, Black Books, French, Travers, etc.

Upon request, I will lookup the prices over time (1959-2015) for any USA coin. If this would be helpful to you in some way, please send me a PM.

Just one example, do you make something like a graph?
Morgan Dollar 1888 either no mintmark, O or S whatever has the most data (adjusted for inflation if possible).

That's a very generous offer across a broad swath of numismatic history! I don't collect US coins, but I hope you get some takers.

For researching recent sales (last several years), the PCGS database is also helpful. For example, the 1888 (P) Morgan: https://www.pcgs.com/auctionprices/details/1888-ms/97183
