There's a seller trying to sell a whole bunch of coins that look like this. I assume it has something to do with what they were stored in, which is kind of scary. These auctions will be over by the time most people see this, but perhaps you can check in the completed auctions and see them if you like. http://www.ebay.com/itm/1915-Mexico...2382245?pt=US_World_Coins&hash=item565c19cd25
Geez Hiddendragon, that's awesome...er, awful. Now if it were a darker blue I'd dig it in a big way. Bruce
All of the 2x2's with the environmental damage have rusty staples, so they were improperly stored , possibly in a moist, salt air location. This seller has plenty more of these beauties newly listed, so you have more than enough time to get your bids in, lol. http://www.ebay.com/sch/Coins-World...ash=item565c19cd25&_ssn=angeladhoward&_sop=10
He has been brought up before i recognize the photos !! i believe his story was were he lived his home was flood or they were found in a flooded home !! Thier was way more to the story but thats what happened he has been selling them like this for over a year some worse then others !!
Well I can't imagine he actually sells any because the coins are in horrible shape and he's charging too much. He should put them all in one lot and charge a few bucks and hope a sucker comes along.
Looks like high humidity storage. Take an old house in the upper midwest or similar environment, have some put a coin collection in the basement, and wait 5-10 years. Humidity and coins are brutal. I helped a dealer friend dip hundreds of us coins trying to save what we could. Maybe ten percent came out without corrosion. Never, ever place coins in a high humidity environment. Just as important, I would never trust a coin from such an environment. It was weird, some coins were black with corrosive toning but would come outok, others didn't look so bad but when dipped were potmarked. If you ever see a flip with rusted staples do not buy unless you are 100 percent positive the coin surfaces are ok.
