I spent 4 hours last night making amiibo coins. Here are the links to the materials I used for the project.
I used a pair of scissors to cut the specific coins I wanted out of the sheets in order to hole punch them, but I’m not going to link a pair of scissors for sake of simplicity.
UPDATE:
I bought the corner rounder and photo paper similar to this.
Printing on photo paper did the trick: no need to do the gloss spray, and it came out in quality easily as good as the Pathfinder Pawns quality. VERY impressed and VERY highly recommended.
The corner rounder didn't work so well. The one I bought for $10 with a 10mm radius didn't cut through the 2mm board that I used. It was basically the same rounder that Vynx used, but they were cutting much thinner board.
I am debating whether or not I want to get a heavy duty corner rounder or not.
EDIT: Got the heavy duty rounder, worked pretty well. Instructions have been updated.
