I now have around 10 of these coins all with identical damage, which I originally dismissed as PMD (Photo of the 4 in best condition below - all in practically AU condition). Even the individual striations are identical (but I can't get the x10 camara to save pictures atm), so I'm starting to believe that this is some sort of minting error.
The error is around the last four oars at the back of the boat…
Note that most oars appear to be intact, as if the scratches run between them. Maybe someone else has noticed this before, but like me has just dismissed it as PMD until now. Your thoughts? Anyone else with similar coins?
Like Ole said, use 1200 dpi to scan, especially for small coins. It takes longer but you'll have a detailed result. Don't go higher than 1200 dpi, then the scan takes too much time and the file size will be too big.
We have a HP Envy 5532 scanner - not sure if it's possible to set the resolution/dpi. Does anyone know how this is done, as the scans I've done so far are worse than the camera on our tablet.
