This is a set of coins I made for my son. We use it to limit screen time and to promote good behavior. When he has good behavior, follows directions, etc. he earns a coin and then the next day he can exchange that coin for minutes of playing zelda. We do 10 minutes per coin and he has an opportunity to earn 5-7 coins per day give or take. Profile is for Sila PLA. I used Inland Gold and they turned our really well. If you want more detail, lower the layer height and line width. If you search around someone else made a model of a Korak into a piggy bank that is a great pairing for these coins.
