What's the difference between 2D and 3D coins?

A “2D” coin is your standard challenge coin struck from a die mold, whereas a 3D coin employs extra tools to emboss your design so it jumps off the coin!

All coins start as 2D. With those two dimensions of the coin, you get a level of raised metal and a level of recessed metal to work with. Typically, this is enough to capture most coin designs, with the raised metal outlining the graphics and the recessed metal filled with color (or left purposefully blank for depth.) In these cases, you’ll be able to run your finger across the face of the coin and feel all the grooves of the design, but nothing will surpass the height of the rim.

3D coins are essentially embossed, with the 3D elements raised and sculpted in relief so they extend up off the face of the coin. A 3D coin needs more than two levels of metal, so a separate mold is created specifically for the 3D elements that turn your coin into a shiny pop-up book. That’s why this option is a separate, extra charge -- and also one of the coolest things you can do with custom challenge coins!
