I'd be interested to know what members think about this little oddity I picked up on ebay. Its a 1972 2c coin that was listed as having a "thin planchet". It certainly is thinner than a normal 2c coin, (see photo), but it also has a diameter that is smaller than a normal 2c coin. So maybe its been struck on a planchet that was originally destined for some other coin. Its composition appears to be the same as a regular 1c or 2c. But does anyone know of a coin this thin? Its strangely very well centred for an undersized planchet but certainly appears to have been struck with genuine dies, albeit weakly. See the piccies. Regular coin on the right for comparison.    |

This is very interesting. If it had been squashed it would have a greater diameter but this ha a smaller one. Maybe you could measure the diameter and compare with other world copper coins.

Yes, I thought at first it may have been a 1c planchet that got squashed but it weighs more than a 1c coin and its very uniformly round.

Can't tell if the surface is rippled. If it is, then the coin's been partially dissolved in acid.
If it's smooth, how do weight and diameter compare to a one cent coin?

The photos on the original listing are probably a bit clearer, and show that the coin appears to have an unusual coarse, speckly surface on both sides.

Seems to me it might have had an acid bath. Pictures will help a lot.

 not trying to be smart nancyc but as it has both an obverse and reverse I don't think it's had a bath but more along the lines of a one cent planchet in with the two's or it was a 2 that should have been rejected due to size etc  |

definitely eaten away with either acid or alkaline

Being dipped in acid etc I don't think explains the difference between the two. The thickness of the plancet is too thin. If the difference was caused by acid surely the whole of the detail would be removed yet both sides still have a large amount showing. The plancet is half the thickness of the normal 2c coin, there would be no detail left to see with acid treatment etc!

 with bjw there is no way acid could thin it out so much and leave details. If it were that thick because of acid there wouldn't be any detail on it what so ever. Acid could not have been the culprit. |

the 1cent is already a thinner coin than the 2c and about 4mm smaller diameter. if it was hit and spread to the same size as the normal 2c by the die, I tend to think it would be much thinner.
also if a planchett smaller than the die did go in somehow I also tend to think it would have an even thickness rather than wedge shape.
im still a newb so could be wrong, but I have huge doubts about it being a 1c planchett.
just noticed something strange looking above the lizards head as well, poor atempt at a forgery?
