Sorry late posting my girlfriend found this in a field haven't tested it yet but looks like an old gold crown with the tooth still in it. Any thoughts?

Ok, here's what I would do....
Contact Dr. Aveni on Lincoln St, (next to Nathaniel Morton School)... he will confirm any suspicions you have...
After that....
Contact Dr. Edward Grimes at Jordan Hospital.
He is an Anatomical and Clinical Pathologist, he will tell you how old it is, as I believe he also has a background in Forensics.
