I stand corrected. Are the hand "punched" out of those sheets?
Small bars with relatively simple designs (think lettering and line art) can be. The A&M bars are done by hand. Anything with a "full face" type design, and larger bars, require more pressure. The Valcambi bars are minted in a coining press.
