And that's why i also still have a small junk box with all sorts of unattributable coins. What could not be attributed yesterday, might simply reveal itself tomorrow !

When I see an encrusted coin such as this I imagine that it's like a hard shell & that a pristine coin is inside, shall I hit it with a hammer & find out  :D :D

is there a way to remove that crust without harming the coin like ultrasound or something?

It's not a crust, but a copper coin. The metal has reacted chemically with other stuff, making the surface bubbly and rough.

Ultrasound is a great way to clean coins, just don't expect miracles. It works only on loose dirt. An encrusted coin (which this coin is not) is best treated with hot and cold baths to crack the crust. You can then work on the cracks with a wooden toothpick. The risk is that the crust contains only dust or tiny scraps of metal.

If you insist on using a hammer, try it out on your skull first. :wall:
