Found this in my Sparkletts bottles. Not sure what I've found. Weighs 2.5 gr.

Nothing more than post Mint damage (acid treated).
You can dump it in the Coinstar machine with the rest of the 'ol Sparkletts bottle. It may get rejected by the machine for being underweight, in which case you can just spend it.
Thin rims a letters usually mean an acid etched coin.
Not unusual, may have been a high school experiment.
Spend it 😉
