Recent Fingerprints Removable With Alcohol?

I see no harm in trying it.If it doesn't do the trick try a dip in "pure" acetone not nail polish remover.Post a before/after pics.

I went ahead and tried it. I didn't get a before picture but I dumped rubbing alcohol onto the coin let it sit for about 20 sec, turned it over and did the same thing. Then I blasted it with water from my sink to remove whatever oils the alcohol loosened up, then I rinsed again with alcohol to prevent water spots and then patted dry gently with a cotton cloth. Worked pretty well. It was a lot to go through to preserve a coin with over 4 billion mintage but hey what they heck. It's a Gem, fairly well struck coin, thought it was worth a shot.
Figures that the best coin in the stack of 25 would have finger prints on it!

Has a nice die clash on the reverse. Where was the prints? Also a tip:take pics before you put the coin in any kind of a holder.I am not good at grading but will guess MS63 red.

well, I bought 25c worth of these from the cashiers register. about half of them are weaker strikes. ie: no defining line between the field and lincoln's throat on some of them. some of them actually had better reverses in terms of strike quality and marks. This one has a lot of die polishing on the reverse but the obverse is indeed a stunner which is what prompted me to "conserve" it, as they say.

edit: this is probably common but the edges are all red-brown from their paper wrapper.

Yes, that is a great-looking 74D. Good call on the conservation.
