Are These Wheat Pennies Cleaned?

I saw that shortly after my first post and edited it accordingly. 2x2 trickery.

#1 looks natural, EF30, hit on date, solid obverse strike(good for that year)

#2 badly cleaned, leaving two tone layers, VF25 details

#3 chemically cleaned(?-Brasso-?), EF35/XF40 details

16 sure looks cleaned - put the other 2 in an acetone soak for a few hours, - can't hurt!!

Take them out of the 2x2's and dust them off. It's difficult to tell what's going on.

1917D - EF, your reverse picture shows a much darker patina than the obverse. I don't see any signs of corrosion.

1917D (2) -EF details, cleaned

1916 - Looks to be a mint state coin. I can see some luster in the reverse. Possible old, light cleaning....pictures..

You've received enough good opinion on the three that I'd rather mention a potential problem, especially with copper coins.

Depending on what that dust and debris is, if you leave it in contact with the coins surface for a prolonged period, especially if there is enough humidity in the air, you can end up with tiny toning spots that almost looks like corrosion.

Buy a can of compressed air to blow that stuff off of them. Also, if you like 2x2's as an option for your raw coins (I do too) I'd recommend that you consider the no staples air tight variety as an option.

They are more expensive than standard 2x2's, but they don't have the dust problem, you won't scratch a valuable coin with a staple, and you won't have clouding, continued toning, or spotting, even on mirror finish proofs.

I use 3 ring binders, 2x2's and airtites....you don't need a special album. The quarter or half dollar size 2x2's accommodate the cent airtites perfectly.
