The 2 holes in the corner were for an inventory plate, not a Vendo logo. You could probably find an era correct sticker to put there.
You have the newer style 63 that offered the can stack, probably produced late 60's early 70's.
$200.00 is an excellent price for that machine, in fact I don't think you could find a nicer 63 at any price.
Glad you had a dolly with a strap on it. We know a guy who hauled his first machine home in a wheelbarrow.
Forgot to mention, yes it has a can stack. The lady mentioned it was originally setup for bottles and was converted to cans.
There are also two rivet holes on the left top side of the machine. Something used to be there, not sure what. Maybe a "property of pepsi" plate? The serial number tag is on it halfway down the left side.
