Linda – Glad you were able to evaluate your Pokemon card values using Mavin! As far as stamps go… you can look them up on Mavin too… you just need to know what details to include. For stamps you want to use the Scott catalog number… and a cancelled envelope sounds like a “First Day Cover” or FDC. So your search might be something like “Scott 945 Thomas Edison FDC“. Good luck!

Hey Toni… I’m not in the business of appraising cards… but if you have a bunch of 1st Edition cards it might be worth your time and money to get them authenticated and graded… especially if you plan on selling them. It’ll cost you $$ to get them graded by PSA, so it usually only makes sense to get the valuable cards authenticated and graded… you can find card prices by clicking on the cards in the Pokemon 1st Edition card set.

Can you please tell me how to get a card expert look at my cards plz
I have all first edition cards

LOL, we’re not buying or selling cards… we’re just a website that tells people what their cards are worth based on cards that have recently sold online. Mavin gives you an estimated worth, that’s all!
