A couple pix from my favorite "dug" Heaton display for this "Sundays Best"
(Discounting the Akroware)
All thrown out as defective marbles, some a little worse for wear
( footballs, pancakes, barbells, double ingot etc...)
I was gonna say clownfish but not seeing any black or the conspicuous white, yellow or green patches, still it could well be a wonky one ....

Most of the newer runs have a blue transparent base instead of a transparent clear base and the newer ones aren't nearly as articulated as the first run (more sloppy) Here's a pic of my best first run, the difference between these and the newer runs is obvious. Still a very nice marble, the older Michelangelo's are getting up there in price. Mines 5/8ths, James is nearly an inch accounting for the looser pattern.
