Mine, shown here before. This has a thread called Cotty, from Sulky, no longer available like this. I called Sulky and the sweet lady sent me the "last spool available anywhere, as far as we know!" from her own collection.
Closest to it she told me is the Sulky 12 wt. cotton which also comes in 'blendables'. Quilt made in mid 1980s, I think; quilted in mid 2000.

That's a quarter, not a penny.
