Thanks for your time.

There is literally no way we can value anything without images and Google has the average price for every one of these based on condition.

I'm going to have to refer you to our centralized thread on that: https://www.pokecommunity.com/showthread.php?t=391812

Please read rules 3 and 4 that are listed in the first post of that thread and then get back to us on the cards you want valuated within that specific thread, thanks! That is the bare minimum of information needed to provide a proper valuation.
