Found This 205 Block...

That top left one is a very nice stamp! If that truly is NH, and were graded as such, it would have a catalog value between $800 - $1,250 (based on my older 2014 Scott Specialized - using specialized by grade section). Even a graded unused OG (which would include stamps with much larger gum disturbances than yours - hinge marks/remnants) catalogs between $250 - $350 (IMO yours is much, much better). Wouldn't be surprised to see it graded as "Jumbo" to boot ... large margins. Others may want to chime in with more current catalog values.

If you are interested in selling that, it would be worthwhile to 1) get it graded and 2) consign it to a reputable auction firm. For fun, you can check to see what certain stamps are selling for in the Siegel Auctions by going to their "power search". You'll see there that graded stamps fetch the best prices. I'm not a fan of grading myself, but it is what it is

It will not sell for those kinds of numbers unless he invests in a certificate/grade for it.

The gum shows an area of adhesion or disturbance. The top and bottom are not parallel . It would not grade well unfortunately and it would not grade as never hinged. Irrational exuberance does a disservice and needlessly raises expectations. I wish it were otherwise because it would be a great stamp to add to the 205 population. My guess is that it is a roughly $150-250 dollar stamp to the right person perhaps. Just an opinion. Again, the gum is not pristine but the biggest detractor is the non parallel top and bottom margins. The PSE would be tough on the stamp and the PF would likely be tougher if they would even grade it. Not sure how PSAG would view it.

I'd send it in for a grade. It won't get a NH designation, but I think it would get an 85, and maybe a 90. I'm not as pessimistic as Rodgcam on this one. Be sure to specify a minimum grade. . you do not want a graded cert on a 75. The cert is well worth the $30 plus postage on this one if you want to sell it.

I received a return email from a guy I contacted. He is a Stamp Dealer in the Des Moines, Iowa area. I asked him if he would help me out with the identification of a few stamps. When my dad was unsure of the exact catalog number, he would mark the container with the number he thought it was and put a question mark with it. Anyway, since I am going to be a while going through all of these items he has accumulated over the course of 60 plus years, this guy better get some of the tools of the trade. Unfortunately for me, there isn't any shops or dealers within 75 miles of me. I will add this block to the others I am taking along and see what he says. I will let you know what I find out.

On a personal note..... THANK YOU!!!!!. Thank you for suggestion, knowledge, and direction you have given me. It has been a big help.

I think specifying a minimum grade is a very good suggestion

Tom,

The guys are commenting on the UL stamp as a disconnected piece. To a grade conscious collector, I get that. However, rogdcams remark about the non-parallel perfs having a negative effect on the grading of that stamp is spot on, imo. What is not being said, however, is that this very non-parallelism coupled with the partial line of perfs in the stamp next to it that makes that stamp IN THE BLOCK more interesting to the technical specialist. Market savvy versus philatelic savvy. Please don't break the block until you understand the significance of that partial row of perfs in the UR stamp, for that is the key to appreciating the significance of the off angle perfs rising up toward the left. We see a fair number of the Banknote issues coming along that have a partial line of "extra" perfs above or below the rest (usually above) but not so many where the orientation of the line is disturbed as in this one. The upper pair in this block tells a technically interesting story about a matter that is not yet entirely settled. Help keep the data available.

I doubt that your dealer friend will be much aware of all this unless you say something to give him pause.

I don't think the skewed/non-parallel perfs and the extra perfs are connected to each other around some, shall we say, production event, glitch, or mishap. The non-parallel perfs such as what we see here, while not normal, I envision occurring without any type of halt to production. The double perfs, I think, are totally normal for this particular run of stamps and were also likely on an untold number of other sheets perforated at this time.

Why did ABNCo seem to run two perforating wheels side by side, producing double horizontal perfs at the top or bottom of the sheets? That is a mystery to me, although I have heard at least one plausible reason for producing these superfluous perfs.

I almost forgot to add that strawberry rhubarb pie is definitely OK with me and cherry rhubarb pie sounds like a good idea, right up there with the wheel!

In general I am not for breaking up multiples to harvest high-grade stamps. It has been suggested that the block needs to be broken for the one nice stamp so it can be sold for a premium. Essayk pleads that the block should be kept intact for the research value to the specialist. Both arguments have merit. Amazingly enough, though, not one person has suggested that the block may have more cash value if left intact! That possibility is totally realistic. Some of the truly sad outcomes of breaking multiples for the graded stamp market has been that the sum of the parts ended up being worth less than the whole.

I cannot think of a single reason to break up the block. If it were mine, I would not do it.
