US Sets Circulated Coins Only
20th Century Series Type Set, Circulated Coins Only (No Gold)
"Circulated Coins Only" Registry Sets accept NGC-certified coins graded AU 58 and
below. These sets recognize that many collectors prefer to complete sets entirely
with coins that were used in commerce. The scoring system is the same as for traditional
NGC Registry Sets, but Mint State coins and non-NGC coins are not accepted. Set
types are listed for every major category of classic United States coins.
