Help with 1906 Japanese One Yen and 1820 Brazil 960 Reis

I believe the first coin is a 1906 Japanese One Yen coin but can't find out much more about it. I welcome opinions and suggestions on how to further research this coin. Yen is a nicely toned uncirculated coin. Portuguese Crown is XF/AU coin.


(I realize now this is a Brazil 960 reis silver 1820-B I will keep studying) The second coin is what I believe is an 1820 Portuguese Silver Crown but I can not find anything on Heritage or otherwise on this coin. Again, any help appreciated.

The Yen looks unc and likely in the 63 range. I do not believe this is a better date.
The 1820 Brazil looks 45 and possibly 50 on a good day.
Experience the World through Numismatics...it's more than you can imagine.
Love the dragon design. A model from the mint in Osaka:
Yours has a cool look to it, though when I was in Japan, there was not as much interest in 'color' coins.
