We all dream of finding a rarity. I had high expectations but if my item is Scott number 594, I'll take it. Hopefully someone with better experience than me can verify which stamp this is. Perf. 11 on three edges, straight edge at top. Measures 19 1/4 mm x 22 1/4 mm.
Thanking you in advance for any information, views, etc will be appreciated.
Thank you to all. I do not have a U.S. special catalogue, only the internet. I've learnt it's not 594 or 596. I do not have another one with perf. 11 to compare to. However, on another site, the dimension for Scott 522 is 22 mm x 25 mm, but mine is 19 1/4 mm x 22 1/4 mm. It was the dimensions in the first place that I looked at 594 or 596. But on line Scott 522 is 22 mm x 25 mm.
