Some marble collectors have been posting amazing group shots of their collections over at The Marble Connection forum.
Thus far most of the pictures show marbles that appear to be machine made, of the high-end, extremely rare and beautiful variety.
I see several marbles in there that could easily fetch $500 or more each, but I doubt anyone is selling those. They look like keepers to me.
I am always grateful when fellow collectors share their best finds with photos like this.
And in this case, quite a bit envious.
