Five new designs are being released each year, approximately every 10 weeks. The ATB designs appear on the reverse of the ATB quarters. Meanwhile, the obverse of the ATB quarter remains virtually unchanged from its appearance during the decade-long run of 50 State Quarters that ran previously to the ATB series.
Mint State ATB quarters are common, but one may be hard pressed to find nicer versions in the MS68 range or above. ATB quarters are remarkably collectible, and they are especially popular among new collectors and all numismatists who enjoy modern coins. In addition to the business-strike offerings, the US Mint is also producing complementary proof examples of each issue.
