About this coinHistory

The 1970-S Large Date Proof was struck at the San Francisco Mint as part of the annual proof set. The combined proof mintage for 1970 was approximately 2.63 million sets, divided between Large Date and Small Date varieties. The Large Date Proof features the same bold, thick numerals seen on the circulation Large Date, with Lincoln's portrait and the Memorial reverse rendered in full proof detail.

The 1970 proof set is notable in numismatic history because it was the last year the San Francisco Mint included a silver-composition dime in the proof set (the 1970-S dime was produced in limited quantities). The cent itself was unchanged in composition, but the broader significance of the 1970 proof set adds context. The Large Date Proof is the more commonly encountered of the two 1970 proof varieties and is affordable for collectors.
