] I found this half dollar, the sides of it are course unlike other half dollars from the time, it also has a dot on top of the eagle, can anyone give me any info on it.
It is pointless to ask a question like that without a photo. No one can answer your question until we can see what you are talking about.
Photo #1 - no idea what that is. Looks like a hole in a sheet of metal. Photos #2 & 3 - looks like the half dollar is a former jewelry piece that was soldered in a bezel and later removed. In that case it has little to no numismatic value and would be worth melt.
