So where do you go for more research about a hidden treasure? There are multiple areas that may offer the information you are looking for.
You can use the Internet. But be careful. Most of the information there is rehashed, and not reliable. You can visit historical associations in the county, or town that you will be searching. Much historical information today is stored on microfilm. Sometimes, when using microfilm, or old newspapers, you can pick up bits and pieces of information regarding the treasure you are looking for. Take notes, ask questions of any lead you may have. The more information you retrieve, the easier your search for buried treasure becomes.
You should also have a reliable metal detector. If you purchase a less expensive model, for approximately $250, then read the owners manual and practice using it, you will become efficient enough to find relics, coins, jewelry, and yes, maybe a buried treasure.
