Found this item a few days ago and I'm not sure exactly what it is. 1 inch diameter at large end of thin copper, pin hole at closed end. Any guesses?
Thanks in advance.

Looks like it may be the bottom of a walking cane

Thank you for input and it does have that dimensional look and I've also considered maybe a guidon pole tip. Just the copper is flimsy and moderately thicker than foil. Again, thank you for your reply.

it's the bottom piece from a flag pole.

Could be likely.
