"Can't Bust'em" Button

Out detecing again for some gold and found this gold button. Cleaned it up a little and read "Can't Bust'em" embossed on it. Did a little Google research, seems this could date back to 1851. A Mr. Herman Heynemann "Can't Bust'em" denim jeans pre date Levi Strauss denim. Seem's Lee denim jeans own the Logo "Can't Bust'em from what I've researched. Any other thoughts out there? Any collectors of these buttons? Enjoy pictures and looking forward to any feedback.
