I'd love to hear what the experts say on it. Me too! I hope it makes it to an XRF . Edited by amida17

My first reaction was also acid-dipped. The wire rim and eroded shapes of letters point that to me.

Some photos of my 1902 Indian Head cent compared with a 1903 Indian Head in the middle and a modern day Cent on the right. I did a web search but didn't find anything about the smaller thin 1902 planchet.    |

The 1902 on the left sure doesn't appear to be acid dipped or worn that much I'm saying a thin planchet. It would be a light or weak strike as the coin presses are set up for a certain tonnage of pressure (around 150-180 tons per inch of pressure, but worn down this much the weak strike has turned into just a worn looking cent. My guess is a legitimate mint error here.

Tonnage for striking cents is around 40 tons per square inch. Combine that with a much thinner planchet and your tonnage drops to under 20 tons. This would result in a very weak strike. With a strike that weak you should not have any of the peripheral legends present and especially not the rims as they are the last things to strike up. The only way to get this kind of detail on a planchet that thin would be to set the presses to a much higher striking pressure (maybe 60 tons for a planchet of this thickness. A thinner planchet means less metal to fill the dies so more pressure is needed.) But what happens when the next normal thickness planchet comes through? Instead of the normal 40 tons, or the reset 60 tons, because of the additional thickness that normal planchet gets hit with with 120 tons or so and things start breaking. No the press would have been set for the normal planchets and if one this thin came through it would show a very weak strike with no peripheral detail and no rims.

If it were acid dipped, with the amount of thinning, I'd expect some details to start to disappear, like the lower right of the C in CENT and the bars in the shield. Back then, did the press reverse with a limit switch or a pressure switch? If a limit switch, I'd expect a weak or almost non existent strike. If a pressure switch, I'd expect the strike to look pretty much the same.

Hmm...I have a few acid-dipped coins. These coins lose a lot of thickness, while still retaining details--but they look thinner and eroded like the first pictures. I also suspect this one was dipped, then got circulated again--but send it to Rick Snow, he'll tell you for sure!  |

On mine, I did send a message to Mr Snow, and it must be bad news, because he has not replied, it has been a week.
Still trying to find the XRF.

I once showed Rick Snow a coin which had extra metal scrap struck into it.
It looks exactly like gold under a loupe. He couldn't figure it out but if there is anyone that knows the series, it would be him.

Keep in mind that, being who he is, Rick Snow lives in a constant deluge of requests for information. I sincerely doubt he has the physical time to answer every inquiry in addition to the rest of his life commitments. |

This coin screams chemical erosion to me, especially the thin to nonexistent rim and denticles which is one of the diagnostics for acidic treatment.

I have one question, though: If it is acid erosion, why is the coin smaller (across) than a regular cent, but still has the rim?

Most of the rim has been dissolved which leaves you with a coin that has an undersized diameter.

Remember the Shrinky Dinks in the late 1960's? This is obviously from that box. Puzzle solved!  |
