One of the challenges we faced with this coin’s super-incuse relief was the master tooling. With a standard design, we can polish the field with ease, as the relief is cut in the negative; in this case, we had to work around the incuse elements of the design, which required a bit more dexterity and focus. But with a bit of ingenuity and some elbow grease, we were able to take this iconic design to a whole other level!

Using the knowledge gained by developing EHR (Extraordinarily High Relief) technology, we were able to go from a standard incuse depth of 0.3 mm to an unprecedented 1.5 mm on this coin. EHR adds extreme height while Super Incuse adds extreme depth, but it’s a similar principle – we just inverted it. Still, we faced a lot of new challenges: there was the manufacturing of a reverse die that included the raised feature; concerns over friction between the blank and the dies (something you don’t have to worry about with EHR); and material movement is much more complex. Fortunately, Virtual Minting is a great engineering tool that helped us understand how to design the blank in order to create this coin.
