Peter THOMAS Pillar of the Community Australia 2830 Posts	Posted 11/09/2007 01:55 am G'day, I thought I read somewhere, perhaps in relation to the 2001 $1 rotated die varieties, that the collar that puts the grooves in, was in a fixed relationship to the non-moving die, which is the reverse side of the coin. Perhaps I'm mis-remembering. I look forward to an answer from someone versed in the technicalities at RAM. I imagine that variations will only be discernible in the coins with interrupted reeding ...

secretsquirrel Valued Member Australia 161 Posts	Posted 11/10/2007 01:33 am The milling/reeding on the edge is in a random position. The collar die gets locked into position and most of the time stays put so on coins like the federation coins where it hasn't moved it can be used to identify what die has rotated. Sometimes the collar die can move, usually after a collar clash or 2. This is when one of the dies wanders and hits the collar die. Some coins with the exact same error can be found to have a rotated collar die, these ones I have collected myself. Report this Post to the Staff
