A 21st-century type coin set consists of one coin bearing each design produced by the United States Mint during the 21st century. That is an enormous number of coins (commemoratives, state quarters, ATB quarters, Sacagawea dollars, etc) in both circulated/uncirculated and proof finishes. We must not forget the material of the coins like clad, silver, gold, copper, platinum, etc.
The NGC type coin registry takes the one type coin for the series approach. Therefore that is only one State Quarter, one America the Beautiful Quarter, one Sacagawea Dollar and one Presidential Dollar required. They only consider coins that were meant for circulation, so no commemoratives and no gold or platinum coins.
I decided to collect a NGC-like 21st century type coin set but, looking always for perfection, my collection is made only by PR-70 coins.
Let's show it, in order of value and year of each coin.
The eighteenth is a PR-70 UC 2009-S Silver "Puerto Rico" D.C. & U.S. Territories Quarter.
It was made of 90% silver 10% copper and weights 6.25g.
The info below comes from https://www.statequarterguide.com/2009-dc-us-territories-quarter-program/
"Following the conclusion of the 50 State Quarters Program, a second one year follow up series was authorized known as The District of Columbia and United States Territories Quarter Program. This separate program featured six additional quarters with designs representing the six U.S. jurisdictions which are not classified as states."
NGC graded 6.694 2009-S Silver "Puerto Rico" Proofs, with 4,946 as PF-70 UC. 996,548 Silver "Puerto Rico" Proofs coins were minted in San Francisco in 2009.
I bought this coin in 2013 for $43.00 and today's price is around $45.00.
"The reverse design features a view of the sea from a sentry box in Old San Juan. Pictured at right is the hibiscus.
The reverse was designed and sculpted by Joseph Menna."
The obverse of each State Quarter bears a consistent design featuring a portrait of George Washington. The design is similar to the prior design of the Washington Quarter series.
