Two Barbers

I'd give the dime a F-12 and the quarter looks solid for VF-20 and possible for VF-25. Both coins appear original and attractive. The quarter definitely is toned but you could try an acetone rinse to see if some of the dark material comes off. My guess is that it won't help but it can't hurt.

Hopefully their bargain-bin status means you got them at a nice price. I like 'em!

isdsms,

Definitely give that quarter a good, long acetone soak (don't do it inside - flamable and the fumes, etc) followed by a thorough rinse. It looks like that residue may be active PVC on the reverse. It will continue to corrode the coin's surface unless removed. The obverse looks like the damage may already be done. I use a round tootpick with softened tip to lightly pry the crud from crevices. This works best right after coming out of the acetone and while the crud is soft.

Had a 1917 Walking Liberty half dollar that came back from PCGS as "PVC Residue" and not gradeable. Sent it back after the bath and it's now in a PCGS MS62 holder.

those are nice crusty original additions! And I agree with Jaobler on the grades.

I also agree with F-12 and VF-20. I think the quarter might even go higher after a nice acetone bath.

Well, here it is! The acetone did wonders for the reverse! It also cleared up the obverse a bit, revealing a nice big scratch. Glad I did it, but will the scratch fade in time?

All and all, I think it looks much better, and still authentic.

Good job cleaning up that quarter!
