[QUOTE="torontokuba, post: 1879292, member: 56793"]Getting there, thank you. Is the coin under this link harshly cleaned, as in post mint damage? Where are the grooves left by pin marks scratching the surface or harsh cleaning? [url]http://www.coppercoins.com/lincoln/diestate.php?date=1960&die_id=1960d1mm007&die_state=mds[/url] I've scratched a coin with various sharp objects. The grooves and gouges are evident. They do not look the same as the raised lines on the 1960 D cent in question. Here is the little helper to your zinc disc... [B]The Authoritative Reference on Buffalo Nickels[/B] By John Wexler, Ron Pope, Kevin Flynn [COLOR=#808080][I]"A wire brush was first used to polish the incused design elements with a diamond dust compound. This process recreated the frosted surfaces of these elements, but also left very fine scratches caused by the brush.
