Scott 594?

Hi I think I have 594 stamp 1 cent Franklin. Can you help me to see if I have the right size..Thanks..Measure 19 1/2 by 22
1/2 by 22mm

gandd07, the stamp you have in your image is not a Scott 545. The 545 is of the Washington-Franklins issued from 1908 to 1922. If you are thinking it is a 594, or 596, you would have to send it to be certified. 596 is a great rarity.

Also, assuming your millimeter scale is accurate, the top image is not 22 mm, nor is the bottom 19 1/2.

Measuring with a millimeter scale is not the way to go in measuring. Take a known flat plate stamp--in the case of the stamp you have imaged, that would be the 1 cent from the first issue of this type of stamps, trim the corners off and then a direct comparison can be made.

Even if you think you have the rare one, certification is a must.

Oh and sorry, welcome to the forum. You will find a lot of good info here.

The way the camera was angled it looks that way, but yes it is 19 1/2 by 22mm.. Thanks

Im sorry it was 2:30 in the morning I meant to say 594 camparing it to the 552.
What is the exact measurements of a 552..??Thanks
