Mis-Printed Holo "Base Set" Vaporeon... Any idea of the price?

[Barboxacon]

I've got myself a holo Vaporeon, from a jungle set booster, which doesn't happen to be stamped with the jungle stamp.

Would anyone know how much this mis-print is worth?

Or does anyone know where I could please find a list of mis-printed cards, so I can check the rest of my collection?

Thanks :)

Oh sorry. I found your price guide. Sorry, not my day for thinking today, I've got the prices, thankyou ^^

Our Price Guide (link at top of page) covers this error:

Vaporeon #12 Holo Low Avg High Trade
Standard Printing 1.00 2.00 4.00 2.00
1st Edition 1.50 3.00 5.00 3.00
The holo cards from the last print run of Jungle all have the same error: They are missing the set symbol! These cards have pricing similar to that of 1st Ed Holos.
