1923 Harding Stamp Please Help

Thank you for the back, gum side photo. The stamp looks to be a flat plate printed stamp. Thus as perf 11 and flat plate, it can only be Scott #610 which has a catalog value for hinged of 50 cents, one dollar if not hinged. Yours as you know is hinged.

No if, please note the word, "if" you had a 613 you would need to send it into a recognized expertizing service such as The Philatelic Foundation (P.F.), the American Philatelic Expertizing Service (APEX) or Professional Stamp Experts (PSE). If the stamp then received a genuine certificate as a 613, you would NOT sell it on ebay. It would need to be handled by a major philatelic firm which handles expensive rarities.

As an aside, in the future, if you remeasure a stamp such as the one here and you start another thread, do mention the first one and why you are restarting it as a new thread.

Now here is someone who did not know there was a rare stamp in their collection but the auction firm found it. https://goscf.com/t/84520 The stamp, an error of color has a catalog listed value of $20,000. Here this stamp has been expertised by the PSE.

You have a listing of 703(b) and show a Siegel Power Search return of a Siegel Sale from 1991 with a price in four figures. In the description Siegel states the item has a P.F. Certificate. Such a certificate from the P.F. or one of the other services I mentioned is need before someone will pay the correct price for a 703(b).

And perhaps as a result of this thread, a new listing has appeared on ebay. $45,000.

Walnut Creek, CA, now. What happened to Oroville, CA?

Well, she is not doing anything 24 others aren't doing on ebay. Currently there are 25 listing of 613, none with a certificate. One pointing out the flat plates have ink on the back (none showed in her photo). I show just those priced at $15,000 and over. They range from there down to $145 (a 613 ? per that listing)

Now as Don points out Google and other search engines pick up SCF threads quickly and a search of jujusales or jujustamps does return these threads about various stamps posted on ebay. Can not say the same for those who have not posted their 613s or other goodies here. It would be better for the hobby if all of those purported 613s were discussed here by ebay sellers using their ebay ID as a SCF member.




Both locations have been used on ebay for as long as she has posted here.

Edited for "not" not naught.

So what exactly is JuJu's motivation for posting here if opinions and advice are NOT what is actually sought?

It takes two to keep this going. Turn on, tune in and drop out.

I think the OP used this board very well to write her product description. Everything including the size, printing and perf counts was discussed by well meaning posters. After the word "if" is removed from those responses then she could pretty well cut and paste her merchandise description and confirm her findings of which stamp it is. I am know we have all seen it many times where posters refuse to acknowledge the posted answers and the word "if". Their research has "proved" their conclusion and any response just confirms that they are right.

The number of people on ebay who are looking to scam is irrelevant to this topic. The others are not posting in SCM and using responses given to them here to find credible-sounding terminology and images to advance their scams.

Well said.

Only option is to simply stop responding.
