Duncan Little Ace is a metal yo-yo made in the early 60s.
Undersized, this one of the first metal yo-yos on the market.
Often these yo-yo separate the metal inside from the metal shell. This one is like that. Makes a lot of noise when you shake it. Aside from that the seal is in fair condition and the yo-yo has a bunch of minor scuffs. You read the gold seal.
