My older brother won a local contest as a kid and got a golden Duncan YoYo.
Seems like Jackie Chan or somebody like him used it as a weapon in one of the martial arts movies.

Seems they are still around but pricey

When in grade school in the early 50's, Duncan Yo-Yo representatives came to our school to sell their products, give a demonstration show on how to do tricks, ability of each type of Yo-Yo and sponsor a Yo-Yo Tricks/Skill contest. In advance of Duncan arriving at the school, most of the boys and some girls, were practicing, during recess periods, their Yo-Yo skills (most of those not practicing Yo-Yo were playing marbles).
A Duncan Yo-Yo was also one of the prizes you could choose from when you turned in two completed Korean War Effort coin folders that held dimes (cannot remember exact amount but somewhere around $2.00 in each folder IIRC).
Those Duncan professionals really blew my mind when I was about 10 years old.
The real question is...do you use your index or middle finger for the yo-yo string?
