Thinking a catch-22:
hardcore collectors already have their collections well documented. Those of us who are “hobbyists”, don’t spend the time to document, and our collections are usually not high-end expensive marbles.
my collection(or what’s left of it) will go to a 3rd party auctioneer when the time comes, the kids have no interest in collecting anything.
it is a neat concept, similar to the numismatic databases, which make sense to me due to the high values of rare coins.
good luck!!
