I went to the DIGSTOCK MINI 2021 IN NC a couple weeks ago. Met a great bunch of people and the event was very well organized. I dug a few nice items and this EAGLE V button. I never heard of one. Turns out it was made for one regiment for one year. 1847-1848 during the Mexican war. They started a regiment of mounted infantry. guess it did'nt work very well. supposed to be a rare button
