Wondering if the US Mint ever produced an Anthony Dollar coin in silver for collectors ? I don't recall ever hearing of any. Correct me if wrong, the only Eisenhower Silver Proof Dollar was minted only for the 1976 Bicentennial; no others exist.
San Francisco made Silver Proofs for 1971-S, 1972-S, 1973-S, & 1974-S. https://coinauctionshelp.com/eisenhower-dollar-value/
Beat me to it! But there were also S-mint business strikes in silver those years. No non-S silver, though.
No, no silver SBA's were struck. I don't know of any trial pieces that may have been struck either. The info on Ike's above is correct.
