I played when I was a kid and amassed a good bit (3,000 or so) from brothers, what I won ( I was very good at this game and we played for keeps) or traded for, and bought. Almost everything was 1955-1970 range. About 1970 I put in 5 large containers and put in closet at parents house. My favorites were Alley Agate St marys plant swirls , especially the one inchers, Marble King Bummblebees and cubscouts (never saw a black widow), and Vitro blackies. Go forward to when I bought my house in 1986. Parents came to see me and said you left something at our house, they brought me my marbles (Thanks Mom - you made me burn up my comic book collection but allowed me to keep the mibs!).
Go forward almost ten years and they sat in my closet while I was busy doing other stuff, for fun my wife and I went to garage sales and flea markets all over the place (geez things you could find in those days). A dealer used to set up at a Florida flea market (under Marble Man moniker)we frequented about every other month and had a huge display of marbles he sold at 2 cents a piece - they were mostly Vitro Anacortes marbles. I stopped and looked at the marbles about 5 different trips before I sprung and bought a 1000 and brought back and shared with soembody who worked for me who wanted them for a display. I also brought out my old marbles to look at, that is when bug hit me and I wondered if anybody collected marbles. The internet growth was in its infancy stage (it cost aabout $20 an hour in those days to use as I recall early 90s ) but I was able to locate a collector or two who tunred me on to some old marbles and I saw old handmade marbles for first tiem in my life. And in those days Bob Block and Danny Turner had their auctions which gave me another source. It just grew from there... bless (or curse) the internet but I would have never had as much fun or met so many nice people wihtout it.
