what do I do? cigarette smoke on proofs.

I received in the mail today some Washington Proofs, Some Silver, some clad, and the 2x2's reek of smoke and it appears some of the proofs are a bit yellow. Would the smoke do that? I want to put them into my Intercept Shield album, but not really in that condition. Should I give them a quick dip, or acetone? Return them? Any suggestions would be appreciated.

If you must acid-dip some to `restore` them only the silver should be dipped.Then acetone after that to rinse away any dip left.If your successful in doing that then you,ve only lower the grade by a point or so overall.A good dip will dull the luster slightly but noticably in many cases.
BTW.Dipping Clad and Copper in anything other than acetone is usually bad,or may have unfavorabe results.
Put em in the intersept sheilds like they are now and they will stay looking just about that way for 100 years.
