Vintage coin collection in brown leather binder

Lost yesterday around 3pm after I swung by the Mall of Abilene on Buffalo Gap Road to check out a few antique stalls. It's a brown leather binder with a red interior, and inside are coins from the 1800s, plus a tiny brass octagonal coin and a rare silver dollar in near-mint condition. A yellow Post-It with my initials 'PP' sticks to the inside cover, and the binder has a dent on the lower-right corner that makes it easy to spot. This collection means a lot to me—it's my late grandfather's and I really need it back.
