A Fast Opinion Is Needed

I had a new collection and need some advices
It contains thousands of US stamps and I am so familiar with them

For a quick start do you see anything here which can be precious?

Thanks

I need to add my topic: I am NOT so familiar with US stamps and I need a methodology for making correct definitions

I am a huge fan of the 2 cent Andrew Jackson (black-jack) stamp... no matter what condition...the one you have is stained with bad centering, but I would still add it to my collection. I also love the 30 cent Franklin and 30 cent Jefferson stamps, even if they had poor centering and heavy cancellations...your franklin is nice but the Jefferson has a tear is in fairly poor condition.

I always liked the 11 cent Hayes stamp, as well, it's another favorite of mine and I always like specimen stamps for adding depth to my collection.

I'm not sure about the first specimen, but I do know that condition is very, very important. I don't see many in good condition, so no "precious" items in my humble opinion.

You posted your topic in the wrong place for starters. What effort have you made to ID your stamps? I see nothing worth much given the poor centering, straight edges and heavy cancels.

Without digging deep, you have some stamps with a little value. Maybe $10-$25. None of the stamps are particularly valuable on their own due to the condition, but most of these are serviceable stamps for collectors not very concerned about condition. The female figure is a cut-out from a postal card - I'd throw that one away. The 1c blue Franklin is in the best condition. It might be most valuable stamp in the lot.

No on the monetary value and scarcity/rarity. A very fun hobby.
