Whats the value of the 50 state quarter collection?
By the end of 2008, all of the original 50 States Quarters had been minted and released. The official total, according to the U.S. Mint, was 34,797,600,000 coins.
This mintage data is just for the coins released for circulation, not the clad and silver proof coins. No matter how you look at it, that's a lot of quarters. Complete sets made up from coins taken from circulation will likely never increase in value.
Sets of uncirculated coins are still in demand and do sell at an average price of $40.00.
