Acetone will be your new best friend.

I would say from a dollar and cents perspective you did well, you could always sell them in a pinch and get more back for them then you paid.
I am sorry but am curious, what does the acetone do?

Acetone will take off the green from PVC. Just soak them in it. Its a way to "clean" them without cleaning them lol

I think you did great- keep the best ones and sell the rest- you ashould come out ahead. I don't think acetone will take off teh green residue- and I also don't think the green is verdigras- its a reaction of teh copper with teh plastic sheets.

I would have snagged that at that price, no doubt. If the acetone doesn't remove the green, try verdi-care. Nice pick up no matter what.

Those Eisenhower dollars are in a Harco album. Since the album cover dating is open-ended (and the pages only go to 1976), it is safe to assume it is an old Harco album, which means it was made with plasticized PVC. That is what is causing the green goo on them.  Regardless, a good deal (if only for bullion value) and I hope you are able to rescue most of them. |

Would any of Badthad's verdicare help? Acetone. Verdicare is meant to be mild by design, a finesse product, whereas these coins need serious organic solvent intervention. It's not verdigris. Acetone is the appropriate cure for the problem, if used intelligently. The only downside is the potential for surface damage revealed by what the acetone removes; a couple of these coins look to be seriously affected.

Thanks to all for the feedback. I'm going to try to spend some time this weekend in the garage to see what I can do with acetone. If that doesn't work, I guess I'll be looking to unload hoping to at least break even or make a tiny profit. Even in horrible condition, I figure I at least have a floor equal to melt value of the 40% silver coins, some numismatic value for the clad proofs and the 1973 uncirculated coins, and face value of the remainder.
Before I acquired this item, I had completed the 18-coin BU clad Ike set (including all 1973 types), and picked this up to see if I could upgrade any I have already. Not really into the silver issues or the individual proofs (I collect proof sets, but not individual proofs), but considered expanding the Ike collection to include these if these coins arrived in pretty good shape. We'll see how the cleaning goes.
Again, thanks for the suggestions. Interested to see how it goes.
Regards,
Brian

Are all Ike Proofs guaranteed 40% silver?

cdgod, No not all Proof Ikes are silver. Infact some uncirculated (for collectors) were silver. The breakdown is as follows with mintage: Uncirculated Eisenhower Silver Dollar Mintages1971-S 6,868,530 1972-S 2,193,056 1973-S 1,883,140 1974-S 1,900,156 1976-S 4,908,319 Proof Eisenhower dollar Mintages1971-S Silver 4,265,234 1972-S Silver 1,811,631 1973-S Clad 2,760,339 1973-S Silver 1,013,646 1974-S Clad 2,612,568 1974-S Silver 1,306,579 1976-S Clad Type 1 2,845,450 1976-S Clad Type 2 4,149,730 1976-S Silver 3,998,621 1977-S 3,251,152 1978-S 3,127,781 |

If the coins have been in the plasticizer long enough for it to have turned green you may have lost most of the numismatic value of the clad proofs and the 73's. The green color comes from copper compounds resulting from the goo etching the surfaces of the coins. So you may find the surfaces of the proofs permanently hazed. |

I had all my early albums like this in the late 70's early 80's & I lost a good chunk of money from damage done by PVC in the Harco albums. Acetone NOW, toss the albums, lest some other collectors puts coins in these death traps. "Buy the Book Before You Buy the Coin" - Aaron R. Feldman - "And read it" - Me 2013!

So, I gave all the coins an acetone bath, and used an acetone-soaked cotton swab to remove difficult spots (being careful to roll, not rub, the swap over the surface of the coin to remove the nasty stuff as advised by a couple of web sites I looked at).
This process was certainly successful in removing the green PVC contamination from the coins. However, at the end of the day, I'll be turning around and selling the coins, hopin to make a small profit. The clad BU coins were well below the quality of my existing collection, so no opportunity to upgrade. As for the clad proofs, I really don't collect individual proofs, and the coins didn't have enough visual appeal and "pop" to me to change my mind and make an exception for my Ike set. For the silvers (BU and proofs), again I don't typically collect non-circulating silver coins, and the coins, while beautiful (especially the shiny silver proofs) each lacked that certain something for me to make the exception to my collecting focus.
Perhaps someday if I find some clad proofs and/or silver Ikes in another auction for a good price, I may reconsider, but for now, the coins from this purchase are being released back into the wild.
Thanks again for the feeback and suggestions. It was much appreciated.
