This article is a little old--obviously the 100 YOM celebration is over--but the information is still useful.
Here is some general information and a link to another website with locations:

Pressing Business --
Collecting Pressed Coins at WDW
First, let me tell you about pressed coins. Specialized machines
take regular coins (pennies and quarters at Walt Disney World)
and, using pressure, a cylinder, and a system of wheels, imprint
a specific design into the coin. The coins become longer,
oval-shaped and flatter than when you started. The design is
permanently imprinted into the coin.
FUN TO COLLECT If you haven't noticed the pressed coin machines
already, take a look around. You'll find them in all the parks
and resorts, as well as at Downtown Disney. The designs are
endless, and you'll probably find new designs with each visit.
The newest machines I've seen are for the 100 Years of Magic
Celebration. In fact, that's one of the neat things about pressed
coins -- you can continue to add to your collection over time.
Another great thing is that it's fun to find the machines and to
make the coins yourself. I love to watch the wheels turning,
pressing the design into the coin as it stretches and flattens
out. No matter how many times I see it, I'm always fascinated.
Good thing too, because making bunches of them for the kids back
home means I stop at lots of machines.
MAKE GREAT GIFTS Kids usually like collecting pressed coins. Most
are fascinated by the way they look, and can't believe they
started as regular coins. While visiting WDW, kids can make the
coins themselves. They can even bring them back for their friends
because they don't cost as much as other souvenirs. They're easy
to transport home, too, because unlike bulky gifts, they take
very little room in your suitcase! With so many different
designs, kids can bring home something different for each of
their friends.
If you're collecting, you might want to focus your collection
rather than try to collect them all. You could focus on one
character, one park, the resorts, or any combination. Your
collection will be totally unique and very personal as you select
designs with special meaning for yourself.
INEXPENSIVE Now to the best part -- collecting pressed coins as
souvenirs probably won't break the bank. Unlike other
collectibles, these are a bargain. A pressed penny costs only 51
cents to make. The cost to make a pressed quarter is only $1.25!
Compare this to the cost of collecting Disney pins, which are
about $8.50 each, or t-shirts, which can cost $10-$20 each.
Remember one thing, though -- once you start collecting anything,
the cost adds up. Don't be surprised at the end of your trip to
find that you spent $50 or $75 on pressed coins and books to hold
them. It's still a lot less than you'd spend on other things, and
you had the fun of finding the machines, choosing the designs,
and making them yourself.
PRESSED COIN TIPS Here are a few tips that I've gathered during
the time my husband and I have been collecting.
*Use older pennies (pre-1982), which look better when pressed.
This is because the older pennies don't include zinc. Zinc can
cause silver- colored streaking in the copper.
*Bring coins with you rather than searching for them when you're
at WDW. Finding a change machine anywhere on property can be very
difficult and takes the fun out of collecting.
*Clean your coins before leaving home using either silver
cleaner, vinegar or, my husband's favorite, a product called
"Never Dull." (You can usually get it at hardware stores.) This
will give a great-looking finished product.
*Carry your coins to WDW in rolls, or you can do what we do and
use plastic mini-M&Ms canisters -- just be sure to tape them
closed or they might pop open when they bounce around in your
luggage.
*Put the coins in your checked airline baggage rather than your
carry- on bag. Airport security stopped my husband because they
thought the canisters of coins looked odd on their scan. Don't
carry the coins in your pockets or you'll set off the airport
scanners.
*Purchase the specially designed souvenir books. You'll find them
in stores at the parks and resorts. They hold many coins and make
a nice way to store and display them. Also, they're not very
expensive (about $7 last time I bought one), so they make a nice
gift when filled with coins you personally made for friends.
*Check the machines each time you visit because they're always
adding new ones. The current 100 Years of Magic Celebration
machines offer a wide variety of new designs.
Finally, if you're one of those people who absolutely *must* know
where the machines are before you go on your trip, there are
websites that provide the information. However, we spent a good part of
one trip following a list from machine- to-machine in each park,
and I can tell you that by the end of the trip, it wasn't much
fun anymore. The spontaneity of discovering a machine while
shopping or visiting a park is great fun, so give it a try.
