Putting the defibrillator on this one. Since I'm on house arrest until the virus goes away I'm bored, so bored I've actually started looking again at sorting out W/F's.
Here are 2 more perf 10 coils I had tucked on a rainy day page.
If legit I believe this one is a pair of 442's

And I believe this pair to be rotary press? Type III? making it (if legit) either 455 or 492 depending on the watermark I won't be able to find, yes I've looked.

The problem I have with getting certs for these is I'm not seeing the ROI. Perhaps I'm looking in all the wrong places but I just checked the sold items on
ebay and the single stamp I posted to start this thread, the *349* which cats at $200 for NH (which this one is)are selling for $10 - $30. I believe the minimum at PF would be $27 for the cert? Or, are these selling at a much lower cost due to not having a cert?
