Is this a 4 sided pyramid or what?

let's see

Compass of the faces of coin
2Af = (2)3.1416(24.1)(24.1)/4
2Af = 912.336348 sq.mm

Area or the rim
Ar = (3.1416) (24.1)(1.78)
...

A invent can be approximated as a cylinder. The surface area of the coin in this case is : 2*pi*(square of radius) + 2*pi*radius*crest
= 2 * pi ( 12.05^2 + 12.05*1.78 ) = 1047.102 sq. mm.
