I picked up this framed cent collection for $5. However some of the cents have corrosion on the edges. Anyway to remove this without damaging the rest of the coin?
Most likely, it is the cardboard touching the edge of the coin. Where the holes are cut our, the inner part of the cardboard without a surface coat/ink can absorb moisture and cause the corrosion. Best to replace the cents, but the same will eventually happen to them also, so replace them with brown examples.
Put the most red, lustrous cents you can find in it. Throw in some steelies as well. Then put it up in your attic. Check it every winter for sweet toning. Repeat if necessary. Pelase note, for best results, do it for 10-20 years.
The verdigris appears to be terminal and the coins aren't particularly valuable. Replacement is your best option. I'm surprized the coins have not been polished. I think nearly every single one of those displays I've ever seen had cleaned coins in them.
I havb a Barber dime with really bad, very hard corrosion. After various soakings for weeks, I gave up and scraped whatever I could get off without totally distroying it. It is a 1913 Barber Dime.
Not bad... this guy is trying to get $14.99 plus $9.00 shipping for his. He doesn't mention if the coins are corroded or not: http://www.ebay.com/itm/Lincoln-Mem...63?pt=Coins_US_Individual&hash=item3f1646aba7
Well yeah, the frame is worth at least 5 bucks, can't say much for the rest. Making something like this would be easy. It'd be a quick stop at Hobby Lobby and the most expensive part of it besides whatever coins you throw in it would be the frame.
