[QUOTE="SuperDave, post: 2315700, member: 1892"]Well, it stands to reason that a grease fill has to originate somewhere other than the die, since they didn't grease dies. :) We can assume a Mint worker didn't put it there, and as often as greasers happen, it is plainly a routine action during the minting process which makes the grease available. Every once in a while they overgreased some part, and the next time the part moved it flung a blob of grease. They grease parts in the same place, the operation action doesn't change, and it's not unreasonable to think the same action might fling the same-size piece of grease to the same spot regularly. This being the obverse die complicates things just a bit, although I seem to recall that obverses weren't always hammer dies with Lincolns. And for that matter, if the problem seems confined to 1943 Wheaties, it could have been a single very solid fill on a single die. That could be as many as maybe a quarter million identical grease fills.[/QUOTE]
