1950-S Possibly 1MM-017 (Just Asking)

yes - I compared it ti the 001, and the mint mark is too far away from the date on my coin. the "s" looks very similar, but the postion dosent match. I'm still struggling with getting better quality images. (new years resolution - get better photo skills). here is an attempt at showing the MM, with the date. thanks.

I'd say it looks a lot closer to 1MM-016 to me, but its hard to tell from your photo's of the mint mark placement (your mm seems tilted backwards a bit, unlike #-016). Try to check for those markers, they look pretty distinctive.

As to your question about die markers and die state...

I have found the die markers definitely change with die state. Sometimes they disappear completely from one state to the next. Or new markers may suddenly appear especially if a die is clashed, polished, etc. Other times (especially with die breaks/cracks), they will become progressively more obvious as a die ages. That is until they change a reverse die on you and really mess you up:). I find it all great fun!
