U.S. coin rolls provide many opportunities for coin collectors. Some purchase new rolls directly from the Mint; others assemble their own rolls; many like to discover the occasional rare coin sandwiched inside a roll of coins purchased from a bank.

This last strategy is known as coin-roll hunting, and it’s become a burgeoning fad. Collectors will go to one bank and buy large quantities of rolls of a single type of coin. They will then search through those coins for hidden gems—like silver pre-1965 Roosevelt dimes—and then return the remaining coins to a different bank. Also collectible are rolls of state quarters, which were first released in 1999.
