Miser coin sorter Owners Manuel
“Basic Model” is pictured and numbered.
The “Deluxe Model” is an
enclosed unit with only minor differences.
This Manuel covers both models.
Penny Miser is individually hand crafted and unique
No two are alike
Your Penny Miser is a one of a kind item
is the front. It displays the Penny
Miser name decal and switch.
The 9 volt battery is mounted to the back of this panel.
1/16“ thick (HIPS) disc with 8 penny holes that is attached to the Motor
Shaft and rotates clockwise while directing
over the Copper Penny Hole and then over the Zinc Penny
Flex Prevent Screws
Helps prevent pennies from getting under the Penny
jamming the operation.
Copper Penny Hole
The Hole in the Main Board that the copper pennies fall through.
Zinc Penny Discard Hole
Hole in the Main Board that zinc pennies fall through
Attaches to the Penny
Miser Housing . Supports the Motor,
Balance Mechanism, Penny Wheel, and
Penny Wheel Flex Prevent Screws.
Both Penny Holes are drilled
into the Main Board. The
pennies ride on the Main Board while
being directed by the Penny Wheel.
Penny Feeder Assembly
Plank, Feeder Tube. The funnel is an accessory that helps feed a larger
quantity of pennies into the feeder tube and is available at
12 Volt DC 10 mA @ no
load reversible gear motor.
This drive shaft
attaches the Motor to the Penny Wheel
Shaft Cotter Pin
Motor Shaft to Motor
Motor Shaft Nut
Secures Penny Wheel to Motor Shaft
the Penny Miser to it’s power source via a 9 volt battery clip.
The mechanism which acts as a
balance scale consisting of the
Balance Beam, Bearing Blocks,
Counter weight Screw & Weights,
and Balance Platform
15 Balance Beam
Pivoting arm of the Balance Mechanism
2 small blocks attached to the underside of the Main Board wwhich
support the Balance Beam.
Bearing Block Screws
Secures the Bearing Blocks to the Main
Board. Allows for
proper positioning of Bearing Mechanism.
18 Balance Bearings
Shaft running through and
Balance Beam Retainer
A small Rubber band connected
to the Bearing Block Screws
designed to buffer the Bearing Beam
Extends through the Balance Beam and allows the addition
and subtraction of weight as needed for calibration.

There is a break-in period. As
the Penny Miser is run, it loosens up and
becomes more accurate.
DO NOT FEED BENT, CORRODED,
FILTHY, GUMMY, FOREIGN COINS, OR OTHER DENOMINATION
COINS INTO THE PENNY MISER.
IT WILL JAM
Attach a 9 volt battery or an AC/DC Power Adapter to
the Power Connector. and turn the Penny Miser on.
If an AC/DC adapter is used, the Penny Wheel will move faster as voltage is
You can safely use up to 12 volt DC.
When learning the machine it’s best to start at a slower speed.
Be sure the polarity on the adapter is positioned so that the Penny Wheel

The Penny wheel must turn at a constant speed.
If it is binding, or slowing, or stopping, first make sure the Penny
Shaft Nut is tight.
Then check the following to determine what is binding.
each Penny Wheel Flex
Plank to be sure it is shimmed properly with washers.
It should be positioned very slightly (about 1/32”) above the
and directly over the path of the Penny
up on the Feeder Tube.
the Penny Platform to
be sure it is not positioned too high and jamming in the Penny
the Penny Wheel and check for foreign material stuck between it
and the Main Board.
PENNIES INTO THE PENNY PLANK ASSEMBLY
Make sure the Penny
Plank is shimmed with washers so that it rests just slightly above the Penny
Wheel. Adjust the Penny Plank so that the Feeder
Tube is lined up directly over the rotating Penny Wheel Hole. To
AVOID JAMMING, be sure that the bottom of the Feeder Tube is positioned very near the Penny Wheel so that only
one penny gets fed at a time.
(To do this you can push down on the Feeder
Tube until it makes contact with and stops the Penny Wheel from rotating), and
then pull up very slightly while twisting the Feeder Tube.
You can feed the pennies directly into the Feeder
Tube or attach the optional funnel to the Feeder Tube.
If using the funnel, feed the pennies by letting them hit & slide
down the sloping side of the funnel which will direct the pennies into Feeder Tube.
Always keep a set of reference pennies on hand that are visually
identifiable. I use 35 shinny pink
zinc pennies and 15 brown copper pennies. I
can distinguish the difference by color so it doesn’t matter if they are heads
up or down. All the pennies I use
are clean and in fine or better condition. I
start running only the zinc pennies. I
start by taking away some counter weights until all zinc pennies fall through
the Copper Penny Hole. I slowly add
counterweights until none go through. (This
is a very sensitive balance and small weights make a big difference)
I then run the copper pennies. All
or almost all should fall through the copper Penny Hole. At this point you are
into very fine adjustments adding or taking away very thin lock washers.
are only two calibrations that you adjust
Adding or subtracting Counter Weight Nuts &
Washers on the Counterweight Screw
is the major factor in varying in calibration.
This may be needed when the sorting rate is sped up or slowed down, or
when you move the Penny Miser to a different location (different slant), or even
as temperature and humidity change drastically.
The washers and nuts are machine screw size #6. Extras are included.
The position of the Counterweight Screw relative to the Balance
Beam) up or Down, along with the height position of Counter Weight
Nuts & Washers (23) are minor factors
The second point of calibration is the height of the Balance
Platform. If it is too low,
most pennies will fall through. if
it is too high, it will get jammed in the Penny Wheel Holes). The
height of the Balance Platform should be slightly above the top
surface of the Main Board so that when an empty Penny Wheel hole
passes over the Balance Platform, the Balance
Platform will move up slightly into the hole but not move enough to
enough to bind.
The angle of the Penny
Platform, when resting in an empty Penny Wheel Hole, is slightly back (towards the Counter
Weight Screw) and slightly
angled so that the leading edge (the edge that the penny first encounters) is
slightly lower than the trailing edge. This
fine tuning can be accomplished by shimming or sanding the bearing blocks if too
much jamming is encountered.
If a penny or even small debris gets stuck under the Penny
Wheel, it will affect the operation or accuracy. If this
happens, turn the unit off. Remove the Feeder Assembly.
Unscrew the motor shaft nut and the flex prevent screws and lift off the
Penny Wheel. Clear the
penny or foreign material. Reassemble.
If the Feeder
Assembly jams, turn the unit off. Try
to turn the Penny Wheel in reverse the distance of one Penny
Wheel Hole by hand or by reversing the polarity on the Universal AC/DC Adapter if
one is used. Turn the Penny Miser back on. If
this method fails, lift the Feeder Tube and clear all pennies.
The Penny Plank may also need to be lifted and re-shimmed closer
to the Penny Wheel.
top reasons why pennies fall into the wrong holes
Dirty gummy or corroded pennies
Get rid of them
Dirty holes in the Penny Wheel
with Windex or soap and water
Nicked holes in the Penny Wheel
Gently sand the nick with very fine sandpaper
Penny stuck under Penny Wheel.
Debris stuck under Penny
Balance Mechanism Jammed
Inspect and remove foreign material.
the Penny Wheel Doesn’t
turn check in the following order
Penny is stuck in Copper Penny Hole
Push the top of
counterweight screw lightly. This
will pop the stuck penny out.
. If you are sure the stuck penny is a copper penny, you can
poke it through
Motor Shaft Nut is Loose (Nut and shaft are turning)
Tighten Motor Shaft
Flex prevent screws too tight
Penny stuck between Penny Wheel and Feeder Plank
Turn power off and rotate penny wheel by hand slightly counterclockwise
Listen to see if Motor is running (If not)
Switch On/Off Switch to On, Check
Power Connector, Check wiring
Penny Wheel is made of High Impact Polystyrene (HIPS)
Clean the Penny Wheel often with Windex or soap and water.
To keep it beautiful, polish the wood surfaces of your Penny Miser with
