I have the Australian coin with the image of Leopold II and the following engraved: GERM-HV-BO-REX LEOP-| |-GRISA. Under the image of Leopold II has depicted the letter "G". On the other side of the coin shows the imperial coat of arms, the number 20 within a device that appears to be formed of branches. Is engraved: LOTH. M. D. HET. 1791. ARCH. AVST. D. BVRG. I found the same coin on the Internet, the only difference was that in the image of Leopold II was depicted on the letter "B".
