The 5-Hole OHMS overprints are covered in this week's blog post. Unitrade de-listed a number of these in 2021 after findings published by the BNAPS study group suggested that a number of them were not ever issued. However, we do not agree that their findings are conclusive, for reasons explained in the detailed post. Although different dies were used for the perfin, it is reasonable to suggest that a given perfin should be genuine if it matches a known certified example. However, we do not have a cretified example from the Carr collection. However we would note that Mr. Carr purchased all of his stamps from reputable dealers and it seems to us that if all of the stamps exhibit the same hole pattern that this would support the notion that they are genuine, since the changes that any two fakes would exhibit the exact same placement of holes is very small. We laid each stamp over top of the others and note that except for the very last perfin lot offered this week, all of these stamps had hole patterns that lined up perfectly with one another. The last lot on offer showed a very tiny deviation in the spacing of the holes. This could either indicate that it is a forgery, or it could be the result of one of the die type differences. Generally speaking, the pattern A's and D's seem to be the most common, with B and F being far less common. The imperf pairs and imperf between pairs are all very scarce with only 200-250 existing of each.
