Pokemon Gold gx Charizard 150/147

My friend gave me this I don''t know much about pokémon or how much it''s worth but he told me it''s worth 750 it''s got a case to protect it and it''s gold with a gold back and on the card it says 150/147 but make an offer with what you think is fair I''m just trying to buy a switch
