Uncommon Magikarp and Cosmo holo Fossil Zapdos

[Mewstor]

Can anyone tell me or estimate the value of the FireRed Leaf Green set uncommon Magikarp (normaly common) and a Cosmo holo printed Fossil set Zapdos (not the normal holo found in fossil set)

The Magikarp is a common error, so no extra value on that.

The Cosmo printed Zapdos is from the Thunder(?) gift set. It's not an error, but is a variant printing.
There not much data on any extra value for it, but i'd guess a 10 or 20% premium would be fair.

actually pop...
that zapdos was not from the thunder gift set. i remember because i got that gift set, and i specifically remember my zapdos not having the error. the error'd one was from packs.

Well, I can't speak for how you got yours, but I got mine from the gift set.
And it makes sense, doesn't it? The cards for the gift set were printed later, when that foil was being used.

So, I wouldn't call it an error.
More of a "variant".
Just like you can get Cosmo foil BS Machamps that were also printed after the foil changeover.

I got my Zapdos also from the gift box.

I have two Zapdos, each with different colored holos. I got both of them out of booster packs.
