Recently started sorting through some marbles my 93 year grandmother left me. I did a little pre-research, found that a good many of them are likely vintage machine made. But a few may be handmade. What I'm trying to figure out is how distinct is the cut off mark on handmade marbles & how it varies. Above are some of the ones I think are handmade, though the yellow one I'm not so certain. Some of the marbles not pictured have very subtle puckers in one spot, like a smooth pinch, is that handmade?
And any info about the picture marbles would be great, thanks!
