How much is a Yu-Gi-Oh God Card worth?

There is only one officially released physical version God Card which is the Blue-Eyes White Dragon from Legend of Blue Eyes White Dragon. Depending on the condition and grading, it can sell for anywhere from $500 to over $1000. On the upper end, a mint-condition PSA 10 can go for close to $2500. As for the other 5 God Cards (Slifer the Sky Dragon, Obelisk the Tormentor, Horus of the Black Flame Dragon, The Wicked Avatar, Sun Dragon Inti), none of them were ever officially released and do not have a designated price.
