Hi, I need help on the old Wheel and Farro Inlaid chips as described by Seymour in his catalogue.What is the difference between the round cut and the square cutchips. The round cut look so much older. The square cut look newer and are usually cleaner. Lots of the square show faint cross hatching on the inlay.Is there any difference in collecting and in cost? Is one worth more than the other? I can't decide whether to collect just the round cut or just the sqauare cut and do I collect all the design and color variations of one or the other? or both? I am tempted in collecting the round cut only and in one color per design only. Help please
