FOUND THESE 21k crushed bracelets while delivering mail.

I was on my break just chilling on a bench when I was something on the yellow on the ground. I thought it was probably gold plated at first but I picked it up and saw a 21k stamp. The weight feels like it’s around 4-5 quarters. What’s it worth?
