I got a Legendary Gold Lightning Dragon and I only bought 3 packs, I have quickly checked the price of this card and it is $300

Here is the packs as I opened them, as you can see the best card in the top left, the rest of the cards where ok but wow a gold dragon

YAHOOOOOOOOOO!

Here you can see the lowest listing of $300 and now I need to decide of what to do with this card as there is only 30 of these cards in existence, do I rent it out or sell it?
