As soon as the coins are struck, a component of the die dubbed the collar stop the empty in place and applies the edge. Once the silverless coins were first produced, the government didn’t see any kind of need to make or to buy expensive brand-new dies or collars. Keeping the reeding wouldn’t hurt anyone, castle figured, therefore the brand-new coins were struck indigenous the very same old dies as the old ones, and reeding continued to be offered as a matter of tradition and also backwards-compatibility. More recent coins v updated design (state quarters, brand-new portraits) likewise have reeded edges.
