Yu Gi Oh Junk Warrior Errata Question

Yes, I know this is a videogame site, but I don't care. I bought a Yu-Gi-Oh! 5d's Starter Deck a couple weeks back, one with an ultra rare Junk Warrior as it's main card. The only problem was, the Junk Warrior I got afterwards in a Duelist Pack 8: Yusei Fudohas a moderately different effect. While the Duelist Pack Junk Warrior gains attack equal to the attack of all level 2 monsters on your side of the field, the Starter Deck Junk Warrior gains attack equal to the attack of all level 2 monsters on the field. They also have the same card number on the bottom left of the card. Was this a mistake or was it on purpose? And how much could this card be worth if it's the only one on the planet?

Yeah this is a video game website but this is the Off Topic forum where we talk about everything but video games. But that being said I don't think anyone here plays Yu-Gi-Oh or even knows enough about the card game to help you. Sorry :(.
