How to Tell if you have a REAL Pokemon ex card

IntroductionAs a seller, the most gemon question I am asked is "How do I tell if my pokemon card is an ex card?" This is actually a very difficult question to answer...
A Pokemon "ex card" can mean one of two things. The card could either be from a new set, or an Ultra Rare Holographic Card.
Cards from a New Set
All of the new sets of cards have the word "ex" in the title. Some examples include ex Sandstorm, ex Fire Red and Leaf Green, ex Diamond and Pearl, and the newest set, ex Diamond and Pearl Secret Wonders. Pictured below is a pack of ex Sandstorm Pokemon Cards. In some cases, the "ex" is hard to spot, but in this case, it is much more clear.

How to tell if you are looking at a Pokemon ex Card
A Bit about ex Cards
A Pokemon "ex" card also refers to an Ultra Rare Holographic card that has the name "ex"after the pokemon's name in the card title. Some examples of cards include "Charizard ex" from the series "ex Fire Red and Leaf Green", "Crawdaunt ex" from the series "ex Holon Phantoms", and "Meganium ex" from the series "ex Unseen Forces." Ex cards are very difficult to find in booster packs, and thus some of them can fetch pretty high prices on e-bay. You should always make sure the card your looking at is really the card you are looking for before you buy. Heres how you can tell an ex card apart from the other cards:
1.) The title of the Cards are different from the normal Cards
The cards are titled like the newer pokemon lv. X Cards.Again, please pardon the watermarks, as I couldn't find my orgionals, so I pulled these from my auctions:

On the left is am Electivire Lv.X from "ex Diamond and Pearl". The title of the ex card (in this case Meganium ex) is similar.
Normal Cards do not have ex in their names. Below is a picture of Meganium from the series "ex Unseen Forces"

Note how the card above just states "Meganium" and not "Meganium ex" like it's ultra rare counterpart.

2.) Pokemon ex cards also have a different border then "normal cards"
Ultra Rare Holographics have white borders instead of the yellow borders like the other cards. The borders typically have a holographic effect of some sort, with the exception of promo cards. Beloware the pictures of "Meganim ex" and "Meganium" again. The border on the edge of "Meganium ex" is a foilly white and has a cool holographic effectwhile "Meganium" has a plain yellow border.

3) Counterfeit ex unfortunately You will occasionally find counterfeit pokemon cards on okay. Whenever you are dealing with a collectable in demand good the issue gees up. The most gemon counterfeits use the yellow border and will loose the holographic effect. These are things all ex cards have with the exception of a few promotional cards (THEY SAY PROMO ON THEM) With pokemon cards in general you can also look at a few key factors to see if your card is legitCan you see through the card when held up to the light?Is the card missing its copy write on the bottom?Is the card significantly darker/lighter than the others you have seen?Is the picture on the card significantly different from others like it?Is the card missing a set number?Is the card in English but have a different back then normal cards?
