in newer electronic coin mechs
it rolls past a magnet to identify if the metal has the correct magnetic qualities by how it effects the coins speed which is detected using optical sensors.
older mechs actually weighed the coin as well a passing them past a magnet to detect metal slugs.

Size, magnetic or not and in some weight.
When you drop it in the coin passes slots of different sizes, which size tells it what value. Some Canadian coins are magnetic. Some will detect the weight by having a little lever on a spring. If the coin is too light it won't push the lever out of the way and will be rejected. Another one will only move if it is too heavy and reject it.

They test for weight, velocity and size. Most coin machines are made by Mars (of Mars Bar fame) who owned a company that used to be called Mars Vendapac who patented a series of coin counting/operating machines and, later, bill (banknote) readers.
Coin and bill machines are very country-specific and have to deal with a range of different currencies.

each coin machine has a tiny camera and takes a picture of each coin as it falls down the machine, then the built in computer does a match to each coin. The tiny robots then grabs each coin and puts the coin in the correct slot. But before this happens the IRS prossing chip reports each coin to the IRS for tax reporting reasons, this information is also reported to the Department of homeland security to make shure you are not a terriorest.

It depends on the age and design of the machine. Some identify size and weight, while others also recognize specific images on the coins' surfaces.

The coin slides down a chute into a weight detecting mechanism. If it is too light it is diverted into the return slot. It goes on to a second weight detector. If it is too heavy it is diverted into the return slot. It may also go into a go/no go size detector. If the coin is good, it goes on to operate a microswitch that turns the machine on.

I would imagine that the people and companies that rent those machines pay a tax to have them there and get a percentage of the money that they bring in. OR The people who own the machines may pay walmart or a mall to let them have them set up in their store in that case I would guess that the only taxes they pay is for the product in the machine.

They measure the amount of bounce. A coin of certain weight and metal will have a bounce factor from a certain height I'm certain of this.

shape,size and weight of the coin.

The m/c sense the coin as per the sensing media it has,e.g. it may have proxy sensor or metel detctor or any other sensor.
