You can get a single $6 coffee at the coffee house.
Or you can get a $6 12oz bag of Swiss Gevalia breakfast roast and make about 20 pots of coffee.
I still buy go to the cafe but as a treat and not compulsion.

Actually, the rippled edge is to make it easier for a blind person to count currency.
The two larger coins, nickles and dimes, have a serrated(Quarter) and smooth(Nickle) edge to separate them.
The two smaller coins, pennies and nickles also do the same thing, with the larger denomination in value having the serrated edge.
This makes it easy to count coins by feel as you can quickly tell quarter from nickle, penny from dime.
