Vintage coin collection album

Yesterday around 3pm I was walking along Grand Ave near the Pueblo Convention Center, just by the Riverwalk entrance, and I must have dropped my vintage coin collection album. It's a small green leather-bound book, about 6 by 9 inches, with a brass clasp and a few scuffs on the cover. Inside are coins from the 1920s to 1940s, tucked into clear sleeves, plus a blue price sticker on the front. On the first page there’s a faint pencil note that reads 'From Grandpa'—this collection is really sentimental to me, and I’d be grateful to get it back if anyone finds it.
