I retired back in 1998 and a Realtor friend, Landon Daniels, collected marbles and invited my wife and I over to visit him and see his collection. He put a quilt on the table and opened his safe and started showing some rare or HTF machine-mades and handmades, saying this one is $1,000; this one $2,500; this one $600, etc. He also showed me his shooter Peltier Superman and a Vacor Serpent and mentioned a "little bit" of value difference, even though they looked pretty much the same - especially to me since I knew zip at that time. He said there are many others that are hard to tell apart so "learn before buying". We went to a SeaTac Show in Tacoma a couple months later (just on the Saturday show day) and looked around - ended up buying one marble - a Marble King Bumblebee shooter for $5. After that, I started looking online and determined that buying packaging (mainly marble bags by MK, Peltier, etc.) was a good way to learn about marbles. Of course there were some fantasy bags being made around that time but they were not ones made by marble companies so I knew something was off. Alan Basinet and I got together online and communicated about these fake bags and started letting buyers on eBay know that they were bidding on fake bags (back then you could communicate with buyers and warn them). However, as we all know, eBay needs their fees so soon they changed it so you could not communicate directly with buyers through eBay. But, you could still see the ID of who was bidding and figure out how to get ahold of them and still warn them. Six months later or so, eBay found that out also and quit showing the ID of who was bidding, etc. and here we are today with a "buyer beware" mentality of eBay (and other sites). Oh, by the way, bags were "the thing" for me and 4,000 plus later, they still are. I did heavily collect Akro corks, metallics, Ravenswood and various other machine made marbles over these 25+ years.
