cash box for an antique slot machine or trade stimulator ???

Description

We are owners of multiple rather large 300 to 500 unit & larger storage rental unit facilities in several states.  Unfortunately on occasion people don't pay their rent and abandon their processions
We are in the storage facility rental business & not collectables or antique dealers and we describe what we see and no but nothing beyond that.  Please don’t ask us where something was made or when, the materials used, or other details as we simply don’t have the knowledge or the time to respond.  All our sales go to a local charity after eBay takes there 13% to 20.4 % commission and fees.
In an unpaid and abandoned storage unit we found this cash box but here are unable to ascertain what it goes to.  Very unusual part and one end has a slanted  design that shuffles the coins to the other end.  Again, we have no idea what this is for and hopefully the coin op people will know
If we receive a nice offer we feel is fair and substantial, we do have that option to end the auction early and sell to that offer.
We combine multiple wins into one box to save shipping costs
. Large items are usually sent FedEx Ground and small items are sent with the USPS.  If you live outside the United States or even within, pay absolutely no attention to eBay's shipping calculator as it is always excessive in cost.  We quote the actual honest cost to ship and we assure you, it is much less that what eBay tells you.
