I wonder if anyone can help me to identify a coin. It is a 1942 George VI threepenny bit.  The curiosity is that it is thin.  2mm only and also lighter than the normal coin (nearer 6 than 6.8g). It seems to measure the same otherwise.  I will post a photo as soon as I am able to take one of a small enough file size.

Please refer to our board "Scanning, photography and image manipulation" for software that allows you to decrease pixel depth. Hint: most screens cannot show more than 300 dpi. At that pixel depth, you can show large pictures.

From your description, this may be a "over-rolled metal" error. Flans are cut from a plate of metal that is rolled to the required thickness. If the thickness is set wrong, the flans are too thin. I can also think of a scenario to do this at home, but it would be convoluted and require special equipment, so chances ae good that it is genuine. A picture would be helpful.

If the coin looks genuine and is British (is it?), you can send it to the UK mint in Llantrissant for evaluation. They are not uptight about errors, will study it and return it with their considered opinion.

An unidentified coin is a piece of metal. An identified coin is a piece of history.
