I didn't find that steel penny...its from my coin collection. I have found several that the only way I could tell was the imprint left in the sand...rusted to nothing after over 65 years in the ground. The site I hunt was abandoned in 1945.
The penny on top is a steel cent from my coin collection (not found with detector). The one on bottom is copper and turned out to be a 42 that was severly eaten by corrosion to where it looked like a 43. After carefull cleaning I descovered the 3 didn't match the 3 on the steel cent.
The ladybug in the 3rd picture actually has a half carat of diamonds in it and 2 small rubies for eyes.
The huge own was found at beach during spring break and is made of brass,
