I found this in my dad's old coin collection. He has no idea what it is. I narrowed it down to 1 Cash - Qianlong from 1736-1800. Exactly which coin it is between 1736-1800 it is very hard to tell. Are these old coins worth anything?
Edit:
I believe it's maybe this coin N#19755 Hartill#22.259: Type F2; radical コ and two-dot radical 辶 in 通 (Old branch) or Hartill#22.262: Type G; radical コ and two-dot radical 辶 in 通 (Old branch)
Edit: I solved it. It's N#19755 Hartill#22.259: Type F2; radical コ and two-dot radical 辶 in 通 (Old branch)
