Got this one -- by mistake -- on eBay for a buck and a half. Thought I was bidding on something else.

Anyhow, the planchet is thinner and lighter than a standard cent. Also about a millimeter smaller in diameter. The coin has a grainy appearance and is a mushy strike, both obverse and reverse.

Question: Is it just struck on a thin planchet or is it off metal, maybe struck on a planchet intended for a Panamanian or Peruvian coin?

to CCF. Most likely acid damage.

Unfortunately, I don't have a scale that could give an accurate weight on this coin.

Acid damage seems plausible. Oh, well, I'm out a buck and a half.

Upon further reflection, I have to express some doubts about the diagnosis of acid treatment. That would not account for the difference in diameter from a standard cent. Additionally, the "etching" seems to be too uniform for acid treatment. I recall from high school chemistry class, lo these many years ago, seeing a demonstration of zinc dumped into hydrochloric acid. The zinc violently bobbed around as it was eaten up. So, I'd expect at least some evidence of pitting, as well as and oxide, or sulfide, or some such coating. I don't know. I freely admit that I'm less knowledgeable that the others on this forum.

At a buck fifty a shot? Nah. I think I'll stick with blackmail and bank robbery.

Zinc is much more reactive than copper, and hydrochloric acid is a very strong acid. The less reactive copper in a weaker acid (such as acetic acid) or a a lower concentration of a strong acid, will react slower, take longer, and will have a much finer surface pitting. (and this coin does show the surface pitting.) And since the acid attacks the edge of the coins as well, it does reduce the diameter.

Thank you, Gary. A clear and detailed explanation. It accounts for everything except the increase in diameter -- 1 mm approx. -- of the coin.

Your first post said it was a mm smaller in diameter.

My bad. I checked again, and it is smaller in diameter, and the rim is perfectly smooth. A senior moment, I guess.

Your post does explain everything. Thank you again.
