Do I Have A 594 Or 596

This stamp is fixed on a real photo postcard. The postcard is from a devastating tornado that happened on June 28 1924 and was mailed but never received a postmark. It has 11x11 perf and measure 19.25mm x 22.5mm. I am getting it authenticated but want to know how much I should insure it before sending it off. Any help would be appreciated

Probably not. Is there any green ink on the back?

That side is pasted down on a post card.

Not even close by what you are showing.

It is fixed to a postcard so I don't know. I do know the 596 was only distributed to 4 cities, one of which being Cleveland Ohio, and Lorain Ohio is just outside of Cleveland. The postcard is also from the year in which the 596 was released. With the history and timeline matching the postcard, and being a perf 11x11, the color, and measurements I'm almost certain it's a treasure. I know the odds are very low of having such a great part of history, but I will remain optimistic until authenticated.

Best of luck but honestly the measurements you show are not what you wrote. It is plain to see.

As to insured value, neither "insured" nor "registered" would cover the value of the item, just a small portion if genuine.

As to the process, you may need to submit the item, have it returned for you to remove the stamp and then resubmit both the stamp and post card before a end result certificate is issued.

I don't know who you will use, a phone call to discuss first would be a good idea. Likewise, if there is an APS or ASDA show near by you may be able to hand the item over to the expertizing service at the show.

rogdcam, I have measured and I know it's difficult, especially since I'm not an avid collector. I came up with exactly 19.25mm. I know the 594 is supposed to 19.75mm. My other measurement is +22mm and the 594 is supposed to be 21.75mm. I know it's hard to tell in my photos, but do you think that it's closer to the measurements of the 596

I contacted PSAG for authentication, they advised me to leave stamp fixed to the postcard. They want me to send it to them but nervous. I will look into bringing to APS or ASDA show together and expert opinion. Has anyone ever dealt with the PSAG authentication and grading service? If so do they provide good service?

Irishclan: You seem to not correctly place the gauge onto the stamp. From the pictures, it looks like your "0" line is 0.25 off. So subtract 0.25mm from the horizontal number. Also subtract 0.5mm from the vertical number, as you seem to make the mistake twice here.
Your stamp seems to be 19 * 21.5
(PSAG would likely lift the stamp from the cover, examine it and place it back exactly where it was before). In your case, it seems like an ordinary 552 stamp so no work will be done I'd suppose.

Irish - A lot, I mean a LOT, of people come here with stamps they are certain are 594 or 596. That is not a bad thing. But the problem always comes from trying to measure fractions of millimeters using a non-precision gauge such as you are using. The perf gauge is fine for measuring perfs but useless for splitting millimeters. Even with that said I am not seeing the necessary measurements from your pics. Keep in mind that the measurements are not the only factors (you seem to be well aware of that).

If you are a gambler and don't mind losing money you may as well submit it though. The bill would only be large if it was certified as real. Otherwise, you will be out of pocket maybe $27 plus shipping costs.

I thought it was hinged to a page, from the scan it's hard to tell. The cancel date should make it easy to tell as well as the location of use. Since it does not appear to be cancelled, it should be compared to a one cent perf 10 and a one cent coil.

thanks to all for your help. I'm glad there is a place for me to get opinions from people with experience in this matter.

Irish,

Based on the photos, I agree that this looks like a 19 by 21.5. I could even make an argument that the stamp is 18.5 by 21.5. Aside from this measuring device being quite imprecise, it has been lined up incorrectly in each photograph.

Irishclan1973, be aware that the cost of the certificate is based upon the catalog value of the genuine stamp. If in fact yours is a 594 or 596 you will be looking at a fee of mid three to low four figures. Of course if it is not a 594 nor 596, the fee will be greatly reduced.
