Any information about how much of these FDC with this envelope were made? As it seems very rare
You should maybe contact them directly as they answer quickly but FDC are not uncommon.
My estimation : hundreds if not thousands edited.
The color/digits is what made them scarced.
Yeah with some collactors they told me the crypto stamps 1.0 FDC are much more scarce and rare than mint once as when they were released not alot people knew about the cancellation to stamp them than of course after that the 2.0 there was alot FDC were people were rushing to stamp them
