I found this penny in change awhile back. I have no idea what causes something like this and it gets even stranger under a microscope.. Any ideas? (Also I know there isnt any value in this coin, just interested ) These are the pics from a microscope on the "bubbled areas"
The copper is electroplated over the zinc core, and if not a clean interface, separation can occur, especially under the pressure of the dies, so bubbles of different sizes, shapes, and quantity is a common feature of these.Jim
Many of the Greybeards like myself and Chris tend to limit ourselves to earlier cents, although I did run into some boxes of 2009 series errors that I couldn't refuse. The younger generation seems to like the later stuff, but all are welcome to collect whatever they wish and can afford to obtain. Jim
I personally can't stand zincolns... especially the shield backs The main series i collect are pre 64 Washingtons due tue the relative affordability.. if I had a bigger budget i'd try for a nice set of morgans tho
