Q&A for How to Value and Sell a Pokémon Card

A "holo" card will have a shiny background on the card art's background, but not on the Pokemon itself. A "reverse holo" card will have the background of the card itself be shiny, but not the card art with the pokemon on it. "Legend" cards have a legendary pokemon on them, and nothing more.

It is for promotional purposes and came with a specific type of pack. They are usually holograms.

If a card is a promotional item, it will say "promo" in a star on the card, usually near the moveset. A "legendary" card, as you put it, will have a legendary Pokemon on it. Sometimes, you need two cards to complete the actual card itself, as it will be printed over two for artistic purposes.

If your card has no rarity symbol, it could mean the card has a printing error, is a fake, or is part of a special/promotional series. Printing errors and special/promotional cards can be highly valued, but fakes are generally worthless.

The most expensive (in terms of average price), Mega Charizard EX, doesn't even go for more than thirty bucks. Mega Venusaur EX is even less (again, in terms of average price) at around seven bucks. I'm not sure what you need 400 bucks rather urgently for, but I hope you can pool enough money together.

There are some cards with an extra symbol that says what set it is from, like black and white or the shield with the lines might be the Arceus set.

No coin, or any other thing, can be rarer than it already is.

A gold star could indicate a promotional card, rare holofoil card, or a rare holofoil LEGEND card, depending on the kind of card it is.

Get another of the same card and check the symbol at the bottom. If the symbols are different, one of them is a reprint.

If you're selling genuinely rare cards for $30, then people will definitely want to buy them.

No. It is uncommon. A black circle means common. A black diamond denotes a uncommon card, and a black star is rare. Silver stars are very rare.

It means it's the last card in the set. It doesn't mean too much, but, to a collector it might. It mostly depends on the card itself.

It depends on which card it is. For example, Shaymin EX is $16 and Tapu Lele GX is $45, but Machamp GX is only $3.

It depends on the card. A kakuna might sell for 50 cents, but a card with a printing error could sell for thousands.

A rare card will always show to be a rare card. The only way to get a "secret rare" is if it is fake.

"Ultra Pro" is actually a company that makes sleeves for trading cards. The card in question must be a card inside a trading card sleeve. Sleeves are pretty cheap and can be found in your local Walmart/Target/etc. or local hobby store, so not much value is added besides the fact that it's in a sleeve.

"XY166" means that it is the 166th promotional card in the ever-expanding set of promotional cards. In this case, XY166 represents a promotional Mega Gengar-EX card from the XY Black Star Promotional Card set.

If the pink figure resembles a Pokemon, the card is most likely from a premade deck in a trainer set. These cards are quite common.

If the rarity symbol is a full silver star, you are in possession of a ultra rare card. If the rarity symbol is not the same color all the way through, it may be a duplicated or fake card. You can check if a card is fake using several techniques.

This card may be a fake. Many fake cards are printed without a set indicator or rarity symbol. Check with someone in person to confirm if it is fake.

That is an XY-Evolutions card. It goes for around a dollar in its regular form and 2-5 dollars in its reverse holofoil form.

It's most likely a rarer card like an EX, GX or a V card. These are known as 'Ultra-Rares'.
