You should have an idea of how many you have, otherwise, he will most likely "stack count" your cards, which is taking a stack of 100 and measuring your cards against the stack. It is a quick estimate way of counting.
The more info you have, the faster your transaction will go, and the faster you will have your money.

when i was sorting through my cards, i came across something. since hl lanturn was reprinted as a rare, would hl lanturns count as a rare also?
lol, dude? Go by what it says on the card.
Any EX, any shining, any holo, any rare, any reverse, any common/uncommon!
