Hi there,
My kids and I are helping sort my Dad's stamps out. He has a wide collection and hasn't really done any work on it since the 70's.
We have a big lighthouse album for loose leaf and are slowly getting them all in for him to give back to him at Christmas.
In the meantime, I may have developed a slight obsession with sorting stamps and looking for variations. I purchased a bulk lot from someone and have found some interesting stamps that seem to have some differences.
I was wondering if the printing on the back of this red 2 penny KGV Australian stamp is part of the stamp of has been printed after? It seems to be embedded. Can anyone identify what it is?
Thanks so much!
