These Jabo Joker Premium marbles feature (two) MINT AS MADE 15/16″ double ingot marbles from the Joker Premium run that was held on 6/13/2010 in Reno Ohio. The double ingot marbles were made by the talented glass artist Joe Schlemmer of Mad Man Marbles. He combined two of my Joker Premium marbles that had black adventurine and formed them into what is called a double ingot. The marbles are in MINT AS MADE condition, never played with but will HAVE a tiny manufacturing flaw. Both marbles are signed by the artist: “MMMJM10” The marbles come in a small cardboard display box that includes two plastic stands for display. I was very fortunate to be a Joker team member for this run and special thanks to MMM for these rare beauties. Please email any questions. USPS shipping.
