Um ... don't think so. When you flatten it out (wire, coin, anything), a lot of what used to be inside (and therefore not surface), will now be on the outside (and therefore be added to the surface area).
Mathematically, consider a circular cross section of wire, with, e.g., a radius of one millimeter. The area is pi sq mm, or, roughly, 3 square millimeters. The circumference, which would be the surface area, is 2*pi, or roughly 6 millimeters. Now squish it down so that instead of a circle, you have a very thin rectangle that is 30 mm long by 1/3 mm thick. The area is still 1 square millimeter, but the circumference is now 60-2/3 mm, 10 times as much surface area as before.
