Mastering the U.S. 'Red Triangle' Stamp Types 

Nice presentation Tara. I am in the same boat as you are. The learning curve is massive for world collectors, and the U.S.P.S. doesn't make it any easier with all the changes and variations that exist in just the U.S. stamps alone.

Excellent presentation and helpful comments! I learned a lot, also what to possibly expect in differentiating varieties of other stamps and what process to follow to distinguish them. Thanks so much, Tara! One of the better and clearer, understandable presentations I recently watched.

Awesome lecture & discussion. I learned a lot.

You bring me back to my youth. I started collecting in 1959 at the age of 10. My guess is that I was about 12 or so when I was able to identify the triangle varieties. Was not until perhaps 18 when I became proficient with the Washington-Franklin issues. Since then have become pretty knowledgeable of both US and World wide philately. The one exception,which drives me bonkers,are the small Greek Hermes Heads. Knowledge may lead to rewards. I may have been 15 when I was at a show in Chicago. I was looking through a dealers binder of used US in the 300's. I needed a #339,the 13c Washington. I picked a nice o out. When I arrived home I examined it. I thought that it may be the rare Blue Paper variety. I sent it in to be expertised in 1988. It came back a genuine blue paper and without faults! This is the only valuable stamp that I purchased for so little and now have a valuable stamp.

Great video! I absolutely love the history!

I just stumbled across your channel today and this video was extremely helpful. I really appreciated the US history you presented as well as the differences between the 4 types. This was very educational. Thanks for sharing and I subscribed!! I'm looking forward to more videos and will check out your past videos as well.

Thank you for this. Well done and informative for someone at my level. I am inspired; that envelope full of triangles will laugh at me no more

My thoughts were why all this information in the first 6 minutes. But as it turns out, it is nice to know the concurrent history surrounding the stamps in question. Overall, a well put together presentation. Looking forward for more content from you.

Hey. What a pain the the butt. Fantastic job. Glad I hung in there.

Wonderful. Thank you

This is why we need AI image analysis! Thanks for a great presentation for a confusing topic, regardless :)

Many Many Many thanks :)

I have been specializing in error and variety coins for over 40 years and I thought that was a rabbit hole. American stamps particularly are a rabbit hole that even I don’t want to go down… lol

Just soaked about 1k stamps, and had about 30 of those. I thought I ID them all, then discovered I accidently had good 20 in a stack under 3 without the triangle (too many drinks and sorting stamps can result in fun identifications later). Been staring at the stack cursing that it's the last ones to ID now from this batch. Nothing worse than already ID's bunch of other ones of the same type then finding out, oh, you actually had more.

Excellent presentation but was wondering if the SG color guide might help on the color variation.

Amazing video btw, one suggestion, mute everyone else in the presentation. People were hot mic'n

I choose not to worry about Iii and IV. I have enough headaches
