Color changeling due to oxidation / environmental exposure. Orange inks are notorious.

Definitely an oxidized C-1. It should be a nice bright orange. A dip in hydrogen peroxide may help revive it some. 2017 Sc: C-1 used 30.00. Good luck!

I do not recommend dipping stamps in hydrogen peroxide.
This is a far gentler method to remove sulfurization using hydrogen peroxide:

Watched the video on Cleaning Discolored Stamps and will give it a try. Thanks for the link.

Love this idea better than a dip, although it has helped in the past. I'm going to look through what I have and see how it does.

I do not disagre, but what happens if a stamp is dipped?

In my experience, it either clears up the problem or it doesn't. I've never ruined one by dipping in peroxide but have cleaned up a few. I don't find those very often anymore.

I tried smaugie's method on a stamp that I have. It didn't correct the issue, but then again a dip is less than 50/50 anyway. I would love to see the dipless method work on one.

I know hydrogen peroxide comes in a % of it. I wonder if a higher % would work faster. I looked on line and found it comes in 2%, 3%, and 6%. What do you think?

I'm gonna repost this here from an earlier thread as it seems relevant.
tl;dr: a ten minute soak in a 3% solution is optimum.

Dennis,
Please let us know how you make out, and what method you use.
Thanks!

I used the method from the video. Placing the stamp on paper towel over a glass of hydrogen peroxide. Worked pretty slick. The colour was almost completely restored.
Thanks for the tips.

1899: I would assume that 6% peroxide would work better but I'm not sure. Good point. I will have to try it when I find some more of these stamps.

Good to see that Dennis had good results using Smaugie's method. Also, it is good to know that 10 minutes in 3% is safe and works well also. Hydrogen peroxide (H2O2) is water with an extra oxygen molecule attached. It's an oxidizing agent and gives up the extra oxygen readily leaving water behind. Even sitting in a sealed container, 3% peroxide deteriorates so, since I go through little peroxide, likely the strength is greatly diminished and may be why my results vary.

I found this in a batch of US airmails. It looks like the C1 Curtiss Jenny but has only a trace of orange. I would appreciate some help in identifying what it really is. Thanks. Dennis
