Texan's Making The Grade Set

Set Description
This is a fun set that I plan to work on that will involve Walking Liberty Half Dollars. It will comprise one coin of every grade on the Sheldon Scale and no Date/Mint Mark combination can be repeated. Every coin must be unique.

Set Goals
The main goal is to have a set of Walkers that show the scale from Poor to Mint State. While doing this, I want to see the relationship of availability in price vs rarity. For example, I anticipate that some of the more rare options will be readily available at the bottom of the scale, due to their affordability, whereas the more common coins will comprise the higher end of the scale.
