T206 Discoloration
 

Any ideas and what caused the discoloration shown. Surface is smooth as the rest of the card. No paper loss. Just curious. Particularly the blue sky. The discoloration does have a distinct shape pattern.

There are quite a few T206 cards that have this discoloration. It was determined that it was the glue used to attach them into scrapbooks. They were eventually successfully soaked, so no paper loss on back, but this telltale discoloration persists.

Brian might be referencing ones similar to these, def affected by a chemical/glue.

Most of these were removed with a solvent to dissolve the glue, which was not water soluble, which caused the discoloration on the front.

That looks like hydrogen peroxide or OxiClean was on the card. I've encountered a couple of cards that ever so faintly smelled of bleach. If you're just dying to know, put the card in a glass of water, let soak an hour or so, then put a piece of red litmus paper in there. If that turns blue then bleach might be a good guess as to what caused that. Maybe someone has done that thinking of giving the player the wings of an angel, in hopes of selling the card at a premium...

I'm not a fan of trimming card edges, I don't think anyone really is. I'm not a fan of bleaching cards. I am good with soaking a card in water. And if a speck of tobacco is on a Polar Bear card, I don't consider soaking and removing that speck as card alteration.

Wow. Never knew that about some glues that were used. Bleed through to the front. And, in fact, closely matches the glue pattern on the back- where it was attached.

Thank you for the inputs. Wealth of knowledge on this forum.

I concur with the above comments...we've discussed this here a few times over the years. At first glance they may look like color variations (printing errors), but they can quickly be explained as cards that have been affected by chemicals or glue, etc. Interesting looking, nonetheless.

Many cards, T206s included, are faded and deemed a color pass miss. But some cards are really color misses. I look to see if the other colors are faded to determine if something has a color missing.
