Evening everyone. For reference, I do not collect stamps for future re-sale or investment purposes. However, I do not like to pay for stamps far over any catalog value if the stamp is not overly rare. I am looking at purchasing a used North Ingermanland Scott#5, Facit #5. Scott lists the stamp at USD42.50, Facit 2020 at 800SEK ( current value 96.64). If I rely on Facit, the asking price of USD50.00 would be a purchase I could handle. If I rely on Scott, a purchase of USD50.00 I would pass on. The stamp looks quite nice, but I am conflicted with the differing catalog prices. I would prefer not to pay over 100% catalog value, but which catalog to use as they seem to differ greatly?

Any thoughts and insights are appreciated.
