Uncirculated Coin

What is the value of a coin collection from the Postal Commemorative Society uncirculated 1965-2006 in albums.
These are U. S. Uncirculated coin mint sets from 1965-2006. Each year is sealed and includes historic U. S. stamps and commemorative postmarks as well as major events from each year. all included in a Deluxe Collectors Album.
They are not U.S. mint sets put together by the mint but uncirculated sets put together by the a private contractor for the commemorative society. They unfortunately have little secondary market value. True coin collectors won’t touch them nor will coin dealers. If a dealer does, they usually offer so little that it is insulting. the 1/2 dollars from 1965-1970 are at least 40% silverr. I would just hold onto them for now, the reason is, collectors now are just waking up to the fact that some of the early clad coins are not that easy to find in high grade. Some day, if your coins are free of bag marks, they may well pay off in the end. It won’t be for a while. Most people have to lean the hard way, that coins from private mints and societies do not far well ,even if made of silver for all they are worth to a dealer is silver price, nothing more.
