Group of Holo's: Looking for Prices

[◘Ins0mnIac◘]

I have been out of Pokemon Trading cards for quite a while, if fact I was out of Pokemon in general until the past year. Because of this, I am behind the times and have NO IDEA of Pokemon cards prices or what is wanted. These are what seem like the most valuable cards I own. I'm curious what they are worth-if anything.

Pretty much all are ranging from $10 to $.50. They're aren't quite expensive as they used to be.

Only the 1st Edition Venusaur, Ninetales, and Zapdos have a decent value (above $15)

Yes, but they aren't very expensive as they used to be. Long ago, used to be ranging from $45 - $100.
