Magic the Gathering - shooting star on card?

Question

My husband has never really played with the Magic cards he's had for about 7 years and told me that I could sell them or donate them if I wanted. I sorted them all by the deck and determined that most of them aren't worth much of anything, but came across one card that was different. The card is from the Invasion deck and is an Island card. There are others in the deck that have identical pictures and text as this particular card, but this one has a silver shooting star on it. Any ideas why? Does it make it the card special or is it just a thing that they randomly put on cards?

Answer 1

The shooting star across the bottom means that it is a foil card.

The older cards had the shooting star, the new ones do not.

Foil cards are a little bit rarer than normal cards, but not substantially. The foil island might be worth about $1.
