What paper work is involved when buying gold bullion?

does gold bullion have something similar to a car title which shows the owner etc. how do you know the gold you're getting is authentic? I'm a total novice, so a detailed explanation is appreciated.

1. A contract with whoever is selling you the gold. You will also more than likely receive a gold certificate verifying ownership.
2. There is no paper work when buying gold. Some bars may have a serial number. Go with trusted Mints and companies like Sunshine Mint,Northwest Territorial Mint,Credit Suisse,Johnson Matthey. You can buy gold from Ebay,bullion.nwtmint.com,Apmex.com and several other legit places.
