<p>[QUOTE="Fallguy, post: 2669843, member: 84739"]From the research I've done, it looks like the last year that mint marks were hand punched into Lincoln Cent dies was 1989. Without hand punching, an OMM would be impossible unless a coin was first stamped at say the San Francisco Mint, then taken to the Denver Mint, perfectly align the detail and then re-stamped. I guess one could take a working die from the Denver Mint, install it at the Frisco Mint and re-stamp a coin that had been already struck with the "S" mint mark die. Sorry, can't think of anything else. Semper Fidelis[/QUOTE]</p><p><br /></p>
