Is there a price check website for cards?

Don't want to undervalue myself on the cards that I have since I haven't traded these before.

Good question, something like that would be very interesting. There is only one exchange app for pocket. Poke trade and you can just look up the wish lists and see which cards are particularly often desired. This way you can at least find out which of the cards are currently popular. But I would really like to know which one has exactly which value.

I think that the value of the cards is currently difficult to determine. I see prices online from 10 to 250 dollars for cards like Oak. But these are all just wishes of the sellers In the end, the buyer always decides what is worth what to you.
