My only concern is, that the coins seem to be a bit too shiny, not like the old-gritty look of the original ones. Maybe I'll use different ones, or use some paint to make them look grittier...
Yeah, just add a layer of wash and varnish. It'll take some of the bling away and make the etchings "pop" more. You could also drybrush them, but that feels like overkill.
