A common edging treatment for veiling, in which they fold the raw edge under 1/4" and then 1/4" again, enclosing raw edge. It is then topstitched to hold hem. The end result is a very narrow "roll" of netting.
A misnomer for the flattened or rounded rim of the 1907 Indian $10, caused by an adjustment to the die to control the metal flow and prevent knife edges from occurring. Reportedly over 30,000 were struck, but all save 42 were melted, creating a rare and valuable variety. Other coins, including proof Lincoln cents have "rolled edges" - they were struck from dies that controlled the metal flow around the collar. The only recognized "rolled edge" variety is the 1907 Indian $10.
