Welcome to the forum hoarder

As stated earlier, that series of stamps is quite common. Always be leery of the word 'rare'. It is a word that is used all too often by sellers on the different online auctions.
I remember when I started collecting seeing ads in the stamp papers (and this is before online auctions etc too) with dealers selling "Rare" Hitler Head stamps. I thought I was worth millions because I had dozens of them at the time - boy, did I learn fast

Hope you enjoy the forum.
