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 nineteenth is a PR-70 UC 2013-S Clad "Fort McHenry" America the Beautiful Quarter.
It was made of 91.67% copper 8.33% nickel and weights 5.67g.

"Following the burning of the Nation’s capitol and other federal buildings in August 1814, British forces attacked Baltimore. Francis Scott Key, a poet-lawyer, witnessed the September 13-14 bombardment of Fort McHenry while under British guard on an American truce ship in the Patapsco River. Seeing his country’s flag still flying over the fort the next morning, he was moved to pen “The Star-Spangled Banner."
NGC graded 1,860 2013-S Clad "Fort McHenry" Proofs, with 903 as PF-70 UC. 945,414 Clad "Fort McHenry" Proof coins were minted in San Francisco in 2013.
I bought this coin in 2013 for $29.00 and today's price is around $25.00.
"The reverse design represents the site during the "Defenders Day" celebration, considered the centerpiece annual event held at Fort McHenry. The fireworks symbolize the "rocket's red glare," linking the fort to its historic past.
The reverse was designed and sculpted by Joseph Menna."
The obverse of each America the Beautiful Quarter bears a consistent design featuring a portrait of George Washington. The design is similar to the prior design of the Washington Quarter series.
