I just got 10 sets of these. I don't know of any others. How unusual/rare/valuable are chips like these -- that is, small key mold chips with die-cut inlays? (An ID would also be nice to know.) The round white circle in the middle, along with the initials (HW, I guess), is a die-cut inlay on all three of the chips! The red chip in the middle is in excellent condition.... .... .. The two end ones are mostly quite nice. The inlays of the end ones are fine; no problems. I don't know how the dark gray and light red colors were applied to those two. All three have good clay.
