MUST READ IMPORTANT INFO HISTORY !!!!!

In 1999 and 2000, the United States Mint struck some state quarters on different alloys 

as part of an experiment to find the best alloy for the Sacagawea dollar to be struck in 2000.

In particular, quarters from five states were involved in the experiment in 1999. 

These include Delaware, Connecticut, Pennsylvania, New Jersey and Georgia.

The Mint struck only a small number of these 1999 experimental alloy quarters, making them exceptionally rare and, therefore, high value.

The 1999 P Delaware State Quarter, minted in Philadelphia, is one of the most valuable state quarters in the Sacagawea experimental alloy series.

One example of this coin, graded was sold at an auction-breaking record of $4,888 IN 2022.
