I always grab marbles at estate sales because, even if they’re not special or particularly important, they sell pretty easily in my antique store in PA. After I grabbed these at a sale for $50 (425 total marbles), I started to notice that they might be good and I think they might be Christensen. Here’s a photo of a bunch. I guess my question is, are they too good to just sell in a Ball jar or are they individually too good for a bulk sale?
