Hi everyone,
My father and I would like to get some feedback on this rather interesting stamp. We have come into possession of an allegedly used Scott #317 on a small piece that has an APS certificate from 1964.
We have never seen or heard of a real used 317 and we are skeptical of this stamp and would like to get some thoughts. We are well aware of the trickery trimming 304's and we have a lot of 304's in our collection, but no 317s other than this one. We plan to contact APS as well to see if this matches up to their records and if it does we will likely send it out for more opinions.
Our thoughts:
- We have examined the stamp under magnification and we don't seen any evidence of a trimmed 304, which would be our first reaction to a 317. The width of the stamp appears correct. Everything looks genuine, but we are not experts.
- The condition is remarkable for a stamp this rare - we are not graders, but the centering is amazing and it looks to be of a finer grade
- We are not familiar with the certificate of this era, but you can see the name of the submitter for expertising – he is well known at least to us. The certificate is water marked, which I can't pick up with the photo of course and the APS is embossed. The certificate smells old and if I keep unfolding it, it will come apart due to age. There is no question the certificate is old.
- The piece was hinged on the back, not on the stamp, but on the piece so it was in someone's album at some point
Questions:
- Does that certificate look genuine? This is the biggest question in our minds. We are definitely going to ask APS, but wanted to get some others thoughts
- Does the stamp look genuine? Probably impossible to tell from this photo right?
- Scott has no value for this stamp, but they do have a dash, which indicates that a known example does exist right? What would be the value of this stamp if it is genuine and how could we even ballpark it? It seems that this would be a very unique stamp and rather difficult to value?
- Have any used 317's been authenticated or sold? It is our understanding that the 317 coils were not put into circulation? We cannot find any evidence on the internet of used 317s.
Thoughts?
