I've just joined, and I decided to dig out my old marbles... well there not very old there about 13 years old so nothing special but better than some of the modern cats eye/milky marbles that are made today. Ideally I'd like to collect old marbles from the 70's and 80's and some Victorian marbles too and clay marbles but they are so expensive, plus I have noticed a lot of ebay sellers are passing off modern marbles as "vintage" marbles. I searched a few charity shops and found a few bags of marbles which look early 90's and they are all different so I was quiet chuffed with that.
I do also have thousands of modern marbles that I bought in a moment of madness because I wanted a large collection of them but its not a good collection when a lot of the modern marbles all look the same, they were cheap and I bought 20 bags of them each bag contained 100 marbles so I have a lot of them.
I'm hoping to build up a decent collection tho rather than quantity.
