Well, let me start with something positive first, congratulations on releasing your own coin with amazing designs. I really like them, so well done! The thing that I do not like is the price, the hologram which looks hand cut and the fact that you hand polished them (which resulted scratches in the coins). It's always better to not polish minted coins as that almost always decreases their value significantly.

I'll not state that your coins are overpriced, because I do not know how much time and effort was put into this. I also don't know how much minting, design creation and hologram making was. Seeing as you only minted 4*4 coins there must be a pretty heavy markup on the coins, which is to bad.

Anyway, I wish you all the best and keep up those nice designs!
