I had gone to a resale shop when I was in college. mostly clothes and stuff, but in a closet, on the floor in a shoe box were Dinky and Corgi toys. I took them to the counter and asked how much. Oh, how about 25 cents each. Okay! well, she starts counting, loses track, starts again and again. Finally, I just say I'll give you ten dollars for the box. I got a book to figure out what they were worth. Some had white tires on them. Got a table at a toy/model show. Sold them for an average of $25 each. wish I could make those investments more often!
