The "apple drop" ones are handmade German, and I see why you like!
In the first picture ,the row of large ones with the white base and the single colored ones might sell well ... some or all appear to be an uncommon "transitional". In that size, all transitionals are uncommon, but there are some which are often found in Canada which are different from ones typically found in the U.S.
The smaller row below also appear to be transitionals. That's our name for certain "handgathered" marbles. "Handgathered" is when the glob of molten glass was dipped out of the heated container with a metal rod and then given a twist and cut off with glass scissors and dropped onto mechanical rollers which did the rounding.
And you also have some transparent based transitionals in your lot ... those can pretty safely be assumed to be from Japan.
I see quite a few more handmade German marbles. And I see at least a few American machine-mades.
I may see some from Amsterdam, and I see one "figure-8" which resembles the American-made Peltier Rainbos but the ribbons are at a different angle, which sets them apart.
The carpet bowls are in a category by themselves.
If you're organizing for sale on ebay, I expect that sorting the bowls and handmades and transitionals out from the rest would be the best. At least in the U.S. You could try mixed lots but if they're too wide of a range, with some really some really common ones, that could weigh down the value you would otherwise have gotten for the better marbles. I see you're in the UK, and I really don't know much about the best way to sell from the UK considering shipping costs.
