I'm not sure but most innova champion plastic is clear (see thru) as far as i know. it might be a special blend for a fundraiser the gold one is fundraiser gold pro plastic rare to the best of my knowledge
The clear was the first clear disc released to the public. 1 of about 50. Im waiting on a response from one of 2 Innova friends, for the exact definition. Not sure of the exact number but i know there wasnt too many of the gold ones. Maybe they will clear this up when they get the chance.
