I was very happy with codysechelski's design, but as an avid collector of US cents, I wanted another that featured as many penny slots as I could fit to separate different varieties. I simply made a mold of the penny slot and crammed a total of 10 in the same 1x3 gridfinity block. I also made a slightly shorter model (about 75% height) if anyone wanted it.
The author remixed this model.
Instead of two sets of each common denomination of US coins, this remix features 10 slots of just cents.
