We have a ceiling fan that wobbles on the higher speeds. We have heard that putting a coin on the blades can help. Which blade, and does it really help? If not, then what will help eliminate the wobbling?

Re: ceiling fan wobble
Try taping a nickle on top of one of the blades start in the middle of the blade (from tip towards motor) then turn it on see if it improves..if not change it to a different blade.. keep trying blades till you notice an improvement. Then fine tune it by moving the penny in towards the motor or out towards the tip. It is a time consuming task but it will work.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Check all your screws especially the set screw at top of fan that goes into rod. Blades could be warped from the water. Ball of fan not set in bracket correctly. When your buying a fan, look for blade pitch.13 degree or better is best. You shouldn't have to use the fan on high unless it's a low-end fan with a low blade pitch. It's costing you more money to run the fan on high. Sorry to get so preachy, I'm a fan dealer .
The fan wobbles cause you bought a crappy Harbor Breeze or Hampton Bay fan. The fan blades need to be balanced with a fan balance kit that comes in the box. You probably threw it out cause you didn't know what the package of weights was for. Get you a Hunter ceiling fan and you won't have an issue with fan wobble, because their fans have better quality control before leaving the factory. If you installed the fan without adequate bracket support- you best get a pro to help you out cause there is no fan wobble help for stupidity.
Interesting situation.. not many people want to down-size a fan. Anyway, reducing the size of the fan blade shouldn't cause a problem - as long as the pitch or angle of the blade remains the same or is less than the original. Increasing the angle with a smaller blade could actually move MORE air than what the motor was designed to do - resulting in overloading and shortening the motor's life in the best case scenario. Worst case scenario - well, anything for electric devices in a worst case scenario usually involves fire, burns and even death (though not likely to happen).
Prior to starting, make sure all the blades are the same in every way including: length, width, angle and weight. A warped blade can cause wobble, too. Stand on a ladder and spin the fan by hand. Look for a blade that is tipped up or hangs lower than the others. Make adjustments as needed to correct (it may not be possible to correct a warped blade - so be forewarned). If any of the variables listed in the first sentence of this paragraph are different from those of the other blades, wobble and motor noise will result. Neither condition should be allowed to exist longer than absolutely necessary. You can minimize these effects by operating the fan at a slower speed. Generally, the blades should be pretty close in all of these variables - but a wobbly fan indicates an imbalance. Weights placed on fan blades can help correct wobble - but can be tricky to determine which blade is the cause.
Ceiling fans need to have balanced blades if they are not to wobble. At
it's simplest this means that all blades should weigh the same, and they
should all be exactly the same shape. But it's not quite as simple as
that, as the brackets that each blade is secured to also have to be
In practice, good quality fans will have the blades
carefully balanced by the factory, and on better quality models the
blades will be matched to individual mounting brackets in which case
there will be markings to identify which bracket goes with which blade
(and also to identify where each bracket mounts to the motor).
fans (almost anything under £130) will not be carefully balanced and so
whether they wobble or not is a matter of pot-luck.
To try and
cure your fault, first remove and accurately weigh each blade complete
with the brackets attached. You can buy strips of self-adhesive
balancing lead to add a gram at a time to the upper side of the tip of
any blade which is under weight. Note that if any blades are damaged,
you must repair the damage before weighing. If any blades are twisted
along their length (normally they're simple flat paddles set at
identical pitch angles by the way the brackets are shaped) then they
must be counter-twisted to match the other blades. Also, check for
manufacturer markings to see whether there are any suggestions as to
which blade goes with which bracket and whether the brackets are marked
to match a particular mounting point on the motor (usually simply by
matching coloured paint blobs).
Once you have checked all that
you can, see if the wobble remains. If it does you should try swapping
the brackets around on the motor: by doing so you'll normally remove the
wobble altogether or will considerably reduce it. You might not achieve
perfect balance, but you may get to a point where the resonances which
cause the wobble offset each other.
A well-balanced fan will not
wobble appreciably at any speed, a less well-balanced example might
still wobble at some speeds and not others.

First loosen the canopy cover and make sure that all the mounting screws are securely tightened, and that the fan is connected securely to the mounteing plate.
After tighteneng all that if the fan is still unsteady, completely clean all the blade surfaces. Then using clothes pins , start adding the clothes pips , like 2 or 3 at a time to a blade about 3/4 out from the center. Try adding to each blade until you compensate for some of the wobbling. By trial and error, increase the weight, shift the position of the clothes pins, and change the weight to different blades to get the best performance. Then when you are satisfied with the correction, tape coins to the top of the blade to replace the clothes pins. again with trial and error, ballance the weight to get the best condition.
Measure from the same spot on the ceiling to the outer most tip of each blade (by rotating to the tape). The distance should be the same, if not check fan blade screws for tightness. You might have to bend the fan blade brackets a little to get the same measurements, if the screws are all tight. If all this lokks good, you might to use a balancing kit...just follow the instructions...it's not too bad to do
put a piece of masking tape on each blade and number them.while you're up there check that mounting screws are tight.switch position of blades,i.e. move #1to #3,see if it's better or worse;switch #2 & #4 or#4  etc. until you find the combination giving you the best 'balance'
you still have a blade that is out of balance. mesure each blade from the bottom side end to the celing in one spot. Do this for each blade when you find the one that is closest to the celing then you have to place the wheight on the edge of that blade then spin it to make the right adjustment then seta stick on weight where the temp. weight is at
Wait? Why would you want to remove the blade? Are they broken? Is the fan unbalanced? Try cleaning the blade. If the fan still wobbles, try tightening the screws. If the fan still wobbles, Unscrew the blade and unconnect the blade from blade iron. Buy the new blade iron. If the blade is broken, Also buy the new blade.
