I found this in one of the 1974 sets I had. What process caused the weird soap bubble pattern? It's on the coin, and the reason it's dark is I was too lazy to set up lighting, and I figured that the lighting might actually kill the contrast.
Why would it only affect one out of hundreds of coins in pliofilm packs, though? Perhaps more specifically, why only that particular cent?
I've never seen anything like that. I suspect not worth much over face but it is pretty neat. My best guess is that there was some liquid in the inside of the plastic in the area of the cent or on the coin itself when it was sealed. That was 41 years ago. I would think that over that period of time combined with the storage it caused this staining. I'd keep it just because it's different.
I've seen this before but not as extreme. Goes to show you, finding these in high grade is not as simple as buying a mint set like most think. Besides issues like this, these are usually pretty beat-up and later die states. Someday collectors will wake-up to Memorial cents.
This is a complete guess but is it possible condensation caused this?? I know it's not worth it but that would be a neat coin to send in to Anacs just to see what the holder says
Is there a hole in the film? Humidity hit the skin of the coin. That happened before or after it was put in the film. We will never know for sure.
If you like bubbles, look for the the early plated Lincolns. The plating technology had not been perfected, and sometimes you find coins with air bubbles between the copper and the zinc core... If you find one of these, you can be just as rich and famous as I am.
