This has been going on since the 1800s minimum, and I sure long before as well. I have found several old brass/copper rings stamped as gold. Often sold by traveling vendors in places like fairs and harvest festivals. That's why you assume nothing is gold until you file into it and test regardless of markings
You are right. I used to detect old home sites long gone in fields. I found a lot of so called gold rings .... stamped that were BRASS from the 1800s. Trying to scam people sure isnt new...... even coins back then. Most of us are smart enough to test our finds before we start out HAPPY DANCE. The new man made diamonds are another scam. The Chinese have found it worth the money to use REAL gold when making fake precious gold coins and silver... even to the extend of aging them. It takes a grader and coin sniffer to ID some of them.
