- #PostalPleasures Presents: How To Use UV Light To Detect Tagging On Collectable Postage #Stamps - Stamp Collecting Tools EP4
We have covered the most common tools needed by a philatelist. now lets look at the nest most common device I utilize, my ultraviolet light.
Lighthouse Brand Dual Wave Ultra Violet Lamp, Long Wave-Short Wave Switchable - www.amazon.com/dp/B005691KTU?...
I use the this model and highly recommend it. Amazon has a great price but the shipping is high at the moment as it comes from Europe.
Its a very versatile tool and I am sure I will overlook some uses but in this video we use the short wave feature of our UV lamp to detect tagging on 4 cent stamp featuring Abraham Lincoln issued by the US in 1965 which is available both:
Tagged - Scott Catalog #1282
Untagged - Scott Catalog #1282a
In this case they both have a minimal catalog value but in some cases tagging or lack there of can mean a significant price difference. This is truly a tool which can pay for itself.
in addition to tagging UV light can be used to detect different levels of #Florescence or #Phosphorescence in the stamp paper. It can also be used to detect color varieties of rare stamps. In particular Ultra Violet Lamps are often used in German stamp collecting
Lastly, wavelength of the UV light is important. US stamps require shortwave lights but some countries require long wave UV light. The light I use is made specifically for stamp collecting and has selectable 254 nanometer Shortwave and 380nm longwave lightbulbs.

Twaskyou sr for all information about taget,stamps.

The long wave setting also makes the light attractive to other hobbyists, specifically those who collect rocks and minerals. Certain minerals fluoresce un long wave UV light.
Stamp collectors consider taggent (the name of the ink) as an additional color of a stamp, albeit only visible under UV light. If it's not there and it's supposed to be (or vice versa), it's an error, and it's probably more valuable, which makes checking for tagging a bit like using a metal detector on a beach. Keep in mind that many of the early issues (post 1962) commonly had tagged and untagged issues: the Lincoln stamps in the video are of equal value either tagged or untagged. Only later did the Post Office become consistent in tagging stamps. All modern stamps are tagged except precanceled stamps (generally used by businesses) and low-denomination stamps (1 cent to 10 cents). The first US test-run was on a 1962 airmail stamp, Scott C62. C62 was originally printed without taggent, but the Post Office later added taggent to some sheets. The first US stamp printed with taggent in the initial production phase was the 1963 City Mail Delivery issue, Scott 1238. Also, the taggent used on airmail stamps is orange-red and the taggent used on general issue stamps (as in the video) is yellow-green.
Enjoyed, thanks
Woooooh!🤔
I want this🤗. .
Lighthouse is the English translation of Leuchtturm, it's the same brand.
Thanks for this information...
That is correct. I will add that the guy in this video mispronounces "Leuchtturm." But since it's a German word and he is American, it's hard to fault him for that.
How long has the post office been adding this to stamps?
Does this work with non machinable stamps? I bought a couple of sheet on Etsy and they look slighty different. I went to a couple of post offices and they look at them said they were good but im trying to more sure.

Cool video. But you never explained what tagging was.
Tagging of postage stamps means that the stamps are printed on luminescent paper or with luminescent ink to facilitate automated mail processing.
@@sandeepsengupta9236 Thank you Sandeep
so does untagged mean it is fake?
@@therealbirthdaybank For many modern stamps, yes.
does untagged mean fake?
No
@@PostalPleasures In some cases it does. Not for the stamps shown in your video, but modern postage stamps issued by the USPS are supposed to be tagged, correct?
