I suppose a new coin would be bright silver and rounder (no damage).
If its in color i think you could a white monogram and white shield (shield has a wooden spina with iron boss ).
Background can be a sort of medium blue (as seen in depictions of Galatians with blue cloaks).
It will be colored for the same reasons as the Athenian coin, which is what I regret about the Seleucid and Ptolemaic emblems.
What was the new one supposed to look like?
