Dug in my car

[takeonestepback]

So dug through my car(I deliver pizza's, so change is everywhere).. and I have like 10 wheat pennies. don't think any are superwow, but there is this one. I don't know what it is, but you can barely see it with the naked eye at all. I didn't want to clean it because I heard the vinegar/salt trick can devalue a penny...but I've tried rubbing it off with a damp cloth,etc... still there.

I only noticed it because I was cataloging and taking pics of the interesting coins I found. New at the whole full blown collecting bit.

Looks like a small spot of corrosion. There are ways to remove it, but I would just store it in a proper holder.

I agree nothing special there. It's in pretty nice shape though.

K, ty. normally I wouldn't think anything of it, but when I zoomed in it has a fairly smooth "s" structure. The stamped S's I imagine would be the same size as the D's, not smaller.
Does the vinegar/salt method work without ruining the coins?
What other methods are there?
I am curious as to I have a bunch of coins that look like they were covered in battery acid/corrosion caked(not from my car). don't think any of them are important though. But then I also found this one..

I highly doubt I'm going to run into a "holy grail" of coins, but some of these are pretty neat looking and I don't want to damage them. That 1966 back looks a little bit raised on the possible double stamp and not by much, but I have no magnifying glass. Using a Note 4 and a led pen light.

Hard to tell what is going on with the '66 from the photos, it might be some foreign substance on the coin but hard to tell. I would never use vinegar and salt on any kind of collectable coin. The only thing I would use for corrosion is a product especially made and tested for coins, verdicare.

From what I can tell, that offset appears to be under the main stamp. thought about if something stuck to the coin(like another one) but can't figure out how it would have transferred past the pillars like that.
I'll assume that Verdicare isn't at the local hobby shop, but maybe I can call a few coin shops in the area and see if they happen to carry it. Thank you!

The '44D wheat looks pretty clean already. What do you hope to accomplish by "cleaning" it? If you remove all the patina, it will ruin what little value it has. That was a very common year so there really isn't much to lose, but, what is the point? As for the '66 memorial, you would need better photos to get a meaningful comment. For corroded, non-collectible coins, run them through a tumbler with aquarium gravel/vinegar/soap and just spend them.

Honestly, the 66 appears to have been stuck to another coin. What you see as going behind the pillars is just an opitical illusion. If the coin had been struck twice the previous transfer would have been smashed. Not to mention it is a different color than the coin. That is the dead giveaway.
