A Golden Sword, also known as a Gsword, is not worth any stat potions at this time. Currently, it is only worth other Tier 7 items. Keep in mind this information has been derived from what I see in the Nexus. Usually, Gswords do not sell because of how common they are, they are more often dropped. I would not suggest trading a gsword unless you are hoping for a very generous buyer or are only looking for low-tier items.
