[QUOTE="justafarmer, post: 2712002, member: 3926"]Mont - thanks for the compliment. I don’t mind you using my post for your coin club newsletter but I would advise against it. It is based on a flawed assumption taken on my part as to the difference of a Hub vs a Punch. Therefore the manner it disseminates the die manufacturing process information is incorrect. I have always differentiated a Hub from a Punch by how the different tools transferred their design elements to the opposing die. I made the assumption a Hub was a tool that utilized a pressing/squeezing force to transfer design elements and a punch utilized a striking/hammering force to transfer a design element. I have now learned the difference between the two is based on the extent, how much, of the coin design they transfer to the opposing die. Cloud in a later post of this thread gave a good explanation on the Mint’s use of a punch for carrying the central design forward into successive years. If the tool was designed to be installed into the screw press for the purpose of squeezing the design into the opposing die, then I was incorrectly making the assumption it was a hubbing tool. If the tool was designed to be struck by another tool as the means for transferring the design to the opposing die, I was classifying it as a punching tool. But as it turns out none of this matters – either way both are punches. But I do think the images do a good job of illustrating how much a coin design can deviate not only year to year but working die to working die.[/QUOTE]
