Can anybody tell me if these are worth anything

It is a Pok?mon staks collection with the original holder, playing board, 2 sets of instructions and checklists and 89 Pok?mon staks inside the file book and its in really good condition

These aren't trading cards or anything to do with the TCG. You'd be better off in the Pokemon general section or using google.

If you ever have any cards that need values then you need to be posting them in the master thread listed below:

This section is still probably the best place to be seeking out values for them on PC, believe it or not.

^ Probably like $30 to $40 for what you've got, based on recent sold eBay listings.

Staks aren't even trading cards though, let alone the Pokemon TCG itself, just an FYI.
