1902 Series Benjamin Franklin 1 Cent Stamps. How To Value?

Hello,

Thank you for the great community. I know NOTHING about stamp collecting or associated value and forums like this are great. What better way for someone like me to get info!

I found a few old postcards at a thrift store my Mom likes to visit. I bought them because it's fascinating having anything over 100 years old. In my little bit of research I see values range tremendously from $20-2,000. I'm sure it's based on rarity, condition, etc.

Where/what would be the best way to value these? I'll probably keep one and sell the rest since I know someone else would appreciate them more than I could.

I know this isn't the "for sale" section and that's not what I'm trying to do. I sort of need to determine a fair value before I can sell then.

Thanks in advance,

Casey

Welcome
The Franklin stamps you show are worth only pennies each; they printed over 11 billion of them. The postcards themselves probably have more value and occasionally an interesting postmark (cancel) can increase market values.
