Source-derived summary

The 50 State quarters (authorized by Pub. L. 105–124 (text) (PDF), 111 Stat. 2534, enacted December 1, 1997) were a series of circulating commemorative quarters released by the United States Mint. Minted from 1999 through 2008, they featured unique designs for each of the 50 US states on the reverse.

The 50 State Quarters Program was started to support a new generation of coin collectors, and it became the most successful numismatic program in US history, with roughly half of the US population collecting the coins, either in a casual manner or as a serious pursuit. The US federal government so far has made additional profits of $3 billion from collectors taking the coins out of circulation.

In 2009, the US Mint began issuing quarters under the 2009 District of Columbia and US Territories Program. The Territories Quarter Program was authorized by the passage of a newer legislative act, H.R. 2764. This program features the District of Columbia, Puerto Rico, American Samoa, Guam, the United States Virgin Islands, and the Northern Mariana Islands.

Origins

The 50 State Quarters program was initially inspired by a 1992 Royal Canadian Mint program, "Canada 125", marking the 125th anniversary of the country's Confederation with a series of commemorative 25-cent pieces representing each of its 12 (at the time) provinces and territories.

Editorial analysis

Why this record matters

The phrase “series of US coins” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q529878. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997, 1999, 2008 and 2009.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
