Crochet Thread 6 Spools Yellow J&P Coats Knit-Cro-Sheen Smoke & Pet Free Vintage

Believed to be size 10 thread, but I cannot verify that - as not all are marked. Please see photos. One spool is marked 10A Canary Yellow, 175 yards, another is marked A64 One spool is a yellow variegated, the others appear to be the same yellow, but not all are marked. These were my Mom’s from pet and smoke free home. Thanks for looking! Review all photos, as they are part of the description and condition. Pre-owned vintage items have been used and stored; expect wear consistent with age and use. Props or measuring devices are not included.
