STATE quarters have only been in circulation for a short while, but if you do find one, they could be quite valuable.
The US Mint produced the state quarters from 1999 to 2008.
Dates, mintages, letter marks, and potential mistakes are the main things you need to watch out for.
The most expensive state quarters, the majority of which are in use, are listed below.
