Thx for all these info. So, those ones that found with Piedmont back aren't legit then? Or they aren't true black/brown/yellow scraps?

Do they come with Cycle and Old Mill back? I am a Cycle and Old Mill backs collector and would like to see whether I should expect finding b/b/y fronts with Cycle and Old Mill backs.
