Identification help needed

Greetings Boys,

I found two coins in my backyard, and i need help.

Both are bronz/brass, diameter ~16-18mm, ~2 grams each.

The round one hase two figures on the back but its in bad shape…

Hi!

1) You forgot to provide also the photo of the other side of the second coin(the aprox. round one).

2) This coin,from its only photo/side you gave us,seems to be a byzantine one. If so and made of silver(?) it is much more interesting because byzantine silver coins are scarce…

Andi👋

P.S.: The other coin may be also a bronze byzantine coin.

They look like late byzantine empire coinage, you can try to find looking backwards in the catalog list:

You could also look for matches at the Wildwinds site of Byzantine coins

I think you can narrow down ypur research to Aspron trachy types
