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 fifth is a PR-70 2009-S Lincoln Bicentennial Cent.

It was made of 95% copper, 5% tin and zinc and weights 3.11g.

The info below comes from https://lincolncents.net/2009-lincoln-cent/

"To commemorate the 200th anniversary of the birth of Abraham Lincoln, four different reverse designs are used for the 2009 Lincoln Cent. Each design is intended to be representative of one of the stages of his life, from birth to presidency.
The fourth and final design represents Lincoln’s presidency in Washington, DC from 1861 to 1865."

NGC graded 14,610 2009-S 1 cent "Presidency" Proofs, with 2,138 as PF-70 RD UC. 2,995,615 coins were minted in San Francisco in 2009.

I bought this coin in 2013 for $38.00 and today's price is around $75.00.

"A view of the half completed Capitol Dome is depicted on the reverse. This view is intended to symbolize a nation torn apart by Civil War and Lincoln’s resolve in guiding the Nation through this period. The designer was Susan Gamble and the sculptor was Joseph Menna."

The obverse, showing the portrait in right profile of Abraham Lincoln, the 16th President of the United States from 1861 to 1865, was designed by  Victor David Brenner.
