The E-Sylum (2/19/2017)
J.L. Lawson & Co makes tops, spinner coins, and other hand-machined products.
Their latest thing is the Tempus Spin Coin, and has been successfully funded on Kickstarter. It's still available in .999 silver, bronze, and copper.
For those of you that are interested in spin times, my average time ranges from 7-9 minutes. Considering the art isn't balanced, the spin is fairly balanced but, keep in mind, this coin wasn't intended for perfect spinning. It's more to help keep you entertained at the local bar.
