A Vintage metal still bank of the 'Streetcar named Desire' bought as a NOLA souvenir circa 1950s-60s, with the slot wide enough for your silver dollars. It has no plug. Presumably it came with one when new, but maybe not.
In v fine condition, it has no dings, scratches, or wear to speak of but it has 2 small blemishes: a spot of white zinc metal powder pokes through the bronze plating that could easily be touched up with a Sharpie (visible in last photo), but I'm leaving that for the new owner to restore. There is a tiny bright speck of the copper-bronze tone on top, due to my removing a bit of remaining price tag 'schmutz' whilst cleaning that kept the plating bright underneath instead of patinating over time.
Measurements: 6 1/2" long X 3 1/2" tall just under 2" deep
