Cancelation dots on stamp

rodeo514

Do these dots form a letter referencing a month or state? Is it in fact a cancelation? Thanks

A "perfin".

They can be company names or other letters, etc.

Companies did this to their stamps to discourage theft.

It is a perfin. Unfortunately, the stamp itself is very common and it is unlikely the perfin will add much, if any, value.

"perfins." The name combines the words "perforated initials" or "perforated insignia." and until now, reading here, I called them pre-cancelled stamps. Good to learn something new and it's only 7:30 AM! From my collection, a favorite.

Found it: New York University Society perfin UNV SOC

Perfins are an area that never seems to get as much attention as it should. The Parcel Post stamp you show looks very fresh and well centered.
