Shameless self promoting:
None of these look 'professional yet attractive' IMOI would like to argue my design is professional and attractive. (for an example look at my current signature which I derived from the design.)
IF NEEDED: you can add text or remove the glow above the "silverwallets" to make it even bigger!
1) I do not agree with you point of view that only your signature is professional and attractive.
I am not claiming mine is. mine is just simple and good. Just different from others.
2)
it is not pure silver coins. It is wallets. You took it seriously! it is coins alright.
