Owner's Description

This is an example of a T1 Blank. Shown is 40% Silver Clad Half Dollar. - The Blanking Process starts when a large rolled sheet of coining material is loaded into the advancement and retaining rollers of the Blanking Press. This press uses several rows of steel punches, which will simultaneously punch out a series of round blanks from the coining material. The cutters on the Blanking Press will thrust into (approx.) 80% of the material, and with the force generated; the remaining 20% will be torn away. When you view edge side of the disk you will see two distinct cut-rings: First is an 80% smooth shear type cut-ring that has a rounded appearance at the entry point of the cut. Second is a 20% jagged ripped cut-ring that is flat at exit point of the cut. The top and bottom surfaces of these blanks remain identical to the sheet of material. These are the chief characteristics that NGC utilizes to attribute this disk as a “Type 1 Blank”.
