Is this card salvagable in terms of any value?

Hey guys, first post here, just curious about this...

I am no Pokemon card expert, these are either my younger brother or sister's cards, but I found this Erika's Dragonair 1st edition that's in pretty good condition amongst a bunch of random cards while helping my mom clean her house a bit.

It seems a bit warped and there is a slight dimple. I put it in a hard case holder for now.
