Look elsewhere to sell gold.
Took some gold jewelry there to sell and they took it away from my sight to determine what was gold and what wasn't.
Came back with an offer of $40. I left and went to a jewelry store that also buys gold and silver. The man did all the testing right in front of me and found items that The Vault said was not gold, tested them and found one that even had the stamp on it. Offered me $80. I took him up on it and got his card to tell others where to sell jewelry and scrap gold and silver.
