Getting a fair shake...

I'm sure it is important to most most people that they are treated fairly.  No matter what the situation is, we want to make sure that we are getting a good deal.  The expression of getting a fair shake is as old as the United States.  Getting a fair shake in the 1700's had to do with the quality of wiskey in the barrels being sold.  A person buying whiskey would put a sample in a bottle and shake it.  If the whiskey frothed and created a head at the top, it was considered to have a low alchohol level.  However, one could shake more or less vigorously, therefore manipulate the outcome of the test.  The term was coin to express the fairness of a deal.
When we buy or sell something we want a "fair shake".  Our goal when buying or selling something from our shop is to make sure that our  customer is walking out happy with the transaction they completed.  The deal has to be a win win for everyone involed.  Buying and selling coins can be a bit tricky.  There are different sources for the pricing of coins, both wholsale and retail.  Our price will ultimately depend on what we can sell the coin for, and when.  Coins that stay in our inventory longer don't command as high of a price that that of a more highly sought after coin that can be sold quickly....
