Most blisters on a single coin?

Very common on early zinc cents from the 1980s. Plating bubbles caused by trapped gas.

This one looks like a plated zinc dust issue. Spendable. Not a plus for the coin.

Either way, an extreme example.

Thanks for the responses!

I know error collecting is not an exact science but I have an observation and a question. Grease fills don't hold a premium until they're extreme examples. MD errors don't hold premiums until they're extreme examples. Off-center errors & die chips same deal. So why wouldn't something this extreme hold a premium? Is it because collectively the hobbyists just don't like seeing plating blisters? Split plating I can understand because the coin is going to rot out but this coin is in good shape besides the error. It is also amongst the first cents to display this sort of error being a 1982. just curious about the rationale on this, thanks.

If someone started a site devoted to "Plating Blisters" there might be interest generated. But for the most part, value is in the eye of the beholder.

Also, remember that this coin didn't look like this when it was minted. It came to look like this over time and may dissolve like we assume "split plating" coins will do. It would be sort of like collecting extreme examples of Post Strike Damaged coins. If this happens, I can see people competing to create the most extreme one.

Thanks Petespockets55, as Coop suggested this looks to be a zinc dust issue and not gas blisters. If thats the case wouldn't this look the same as when it was struck?

also, in hand and not under magnification this coin has a some great eye appeal with a kind of shimmering sparkling look. I know I know, beauty is in the eye of the beholder :)

I don't believe it would since the die wouldn't have had these bumps on it. IMHO, the flat areas of the field and smooth areas of the devices would still make the coins appearance look the same after minting. I think dust may have interfered with the copper bonding to the surface of the zinc, allowing the copper to pull or be pushed away over time, or the zinc to decompose under it.

EDIT: I just noticed your last image seems to show the bubbles arranged in a linear pattern over Lincoln's face. This linear pattern makes me think these "bubbles" are roller lines in the underlying zinc that is decomposing unevenly.
