1980s S and West Point cents?

[eagames]

Did they make non proof bus strike cents in the 80s in the S mint and West Point? If they did do mintage numbers exist and is there a way to tell them apart? I know they made cents without mintmarks in 65-67 in other mints without mintmarks.....

The P mintmark, discontinued after the war, reappeared in 1979 on the Anthony dollar. By 1982, it had appeared on every other regular-issue coin except the cent, which still bears no P mintmark. The circulating cents struck in the 1980s at San Francisco (except proofs) and West Point also bear no mintmark, as their facilities were used to supplement Philadelphia's production. Given the limited numbers produced at each facility, they might have been hoarded as collectibles.
