Ten Coin Proof Sets From 1999

If you've been eyeing ten coin proof sets from 1999, beware that these sets are not from the US Mint. Ten coin proof sets have shown up in the marketplace containing a 1999 Proof Anthony Dollar. However, these are sets made from private individuals who are combining a genuine 1999 Proof coin into a 10 coin holder from later sets. There were never any ten coin proof sets offered from the US Mint during the 1999 year. However, a ten coin proof set was introduced in 2000. The genuine 1999 sets contain coins with an “S” Mint Mark from the San Francisco Mint.
