ANA Encased Buffalo 2009 World's Fair of Money

Above is a 1935 encased Buffalo Nickel that was issued by Krause Publications for the 2009 ANA World's Fair of Money held in Los Angles, CA. at the Los Angles Convention Center. They were given to YN's who entered in the Treasure Hunt held during the show. There were gold colored encasements as seen above and black encasements seen below. The gold encased nickel has a 1935 buffalo nickel and the black has a 1936 buffalo nickel. The encasement is 38.0MM in diameter and 2.0MM thick.

I believe that they were made by Penny Press Mint and am attempting to verify that and if possible find out how many of each were made.
