A set of WWII coins that I own (It's a grainy picture, so pictures of individual coins on request)

From top left to bottom right: American wheat penny 1944, British half-penny 1942, Soviet 1 kopek 1940, Nazi 5 pfennig 1940, Japanese 10 sen 1942, and Italian 20 centisimi 1940

:D

You might have good pianist hands
May I suggest you take lessons?

I haven't taken lessons, but I have watched tutorials and I've learned a lot of songs (most of which I haven't completed)

Yeah lessons will help a lot
I have a LOT of experience, so I could probably give you some tips if you want
