Antique Tooled Leather Snap Coin Purse circa early 1900s with Provenance RARE

From my MILs estate...

Tooled leather with stitches around edge
Snap closures
Three compartments
Measures about 3.5" tall x 3" wide

Includes a note "My Father's purse" written on paper; the other side of the paper has number calculations on it.
Snaps are copper and have green corrosion, as shown in pic. 
I couldn't get the snaps to snap -- that might be because of the corrosion or because I'm not strong enough.

See all pics as part of description.
