Identify This US Stamp 70d Or 78c With Thin Paper?

I recently acquired this well-centered early 1860s classic US stamp which I am having PF certified. It has original gum on thin paper and appears to me to be Scott 70d the pale gray violet variety. What is your opinion as best as you can with scans pictured below. Were 78 varieties printed on thin paper. If so I am not aware?

BlackJack2271....according to SCOTT and MICARELLI, if you are sure thin paper....could only be 1 of 2 varieties.
#70c or #70d .
Well worth getting a cert!

I am curious to understand if the stamp has a Scott Value of X and the cost of certification is 0.05 X, is it worth the certification if the true market value is 0.05 - 0.10 X of catalogue value? This is an obvious simplification of the question, but would some of you care to discuss the merits of it?

By the way thank you for posting the gorgeous stamp and I do hope to hear the results of your certification.

I will be having the PF opinion soon as it was submitted to them in early Nov.
I asked that it be graded as well. If 70d it is surely a 5 figure stamp so PFC is required here.
I was able to gingerly remove the stuck paper from the OG without creating a thin.
Chipshot thanks for your comments and I will post cert. when it arrives.

An early Steel Blue 70b was also printed on thin translucent hard paper as I recall. So that this stamp could be 70b Steel Blue

Sorry, this is not steel blue. It's also not pigeon blood pink.

BlackJack, yours is a beautiful stamp. If, however, you want to, go to the PF site to look at their Steel Blues. The color difference from yours is quite striking.

No disrespect to Hy Brazil and Dry Top but the color of. my 24c Washington is closer to the photo below and not like the OP photo. This could be one of the few Original Gum Steel Blue 24c Washington known on thin paper.

I am confused BlackJack. I thought that you are the OP? In any case I wish you the best of luck. I believe that it will come back as a normal 70 or 78 (I cannot tell from the scan) reperfed on the bottom. If you specified a minimum grade you can escape receiving a low grade that drives down the market value. Cannot wait to see the results!

thanks for posting this nice stamp of the scott 70s Series. I think its unused you can see the partial glue on the back of the stamp. the front pictures is to blurred to determine if some ink was removed. the colour is imo not steel blue 70b. The two varaints that looks closest to your stamp colour is scott 70 or 70d.
Can I ask you how you handle it with the PF in N.Y? Did you do insured shipping (I ask because this stamp could be a 70d and worth 30-40 000 usd)?

Yes I have been in contact with the PF and they are deciding between certifying it as a 70b steel blue or 70d pale gray violet. to say the least I am super excited about the value it may have.

I should find out soon and will post the opinion here. I send all my rare stamps to the PF using Fedex and never had a problem.

Best of luck. I cannot wait to see the certificate. I never realized that they would state verbally that they were considering multiple choices prior to a final decision and certificate. Good to know.

Edit: I should add that this would be an extraordinary find. I do not know how many of either of these mint stamps have been certified by the PF but the PSE has only certified one mint 70b and zero mint 70d's. What are the odds that a mint copy existed all of these years without a certificate. Almost beyond belief!

Good luck, BlackJack2271! Standing by the see the cert!

Yes I also am surprised, or more accurately shocked, to hear that the PF was offering up verbal preliminary opinions before issuing a certificate. It is completely contrary to my image of that organization.

This stamp was submitted as a 70d pale gray violet based on the thin paper. Just to clarify, I said it may also be an early 70b steel blue stamp. There was nothing the PF said officially to confirm or deny my assumption.
