Correct and that way they only had to make one master hub. Then they only had to make one type of die. If one of the other mints needed more dies they didn't have to make any up special, just take some of the unhardened dies already on hand, punch the proper mintmark into them and ship them out.
The down side was the huge number of dies, especially cent dies for Denver that had to have D's punched into them. For example in 1983 they had to hand punch a D into over 6,000 cent dies. Is it any wonder they decided to eventually start having the mintmark on the master hub.
