Quote: Last week I moved all my error coins from 2x2's to saflips and in doing so I very closely looked at each one. Some of the decimal Struck Through Grease that I had put aside turned out to be rim machine damage. I would look very closely for parallely lines in a circular motion. Would appreciate thoughts on this one. It appears that the coin may have been seated incorrectly in the rim machine resulting in the loss of text / flora? See what appear to be EXIT points (black arrows, pic 5). The obverse appears to have similar but less intense marks (plus the impact of a coin counter at some stage ). Excuse the pic plethora.

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 11/09/2012 6:51 pm The rims of a coin are formed before it is struck, the blanks are force-spun through an upsetting mill which forms the protorim. The following example is obviously not an Aussie coin but it will give you an idea of the difference between a completely flat blank and a planchet with protorims, left to right is the blank and then planchet. The rims are then fully formed during the striking of the coin. Circular scratches next to the rim are typically caused by counting and rolling machines, the obverse is also damaged on this coin.

enworb Pillar of the Community Australia 4411 Posts	Posted 11/09/2012 9:26 pm Yeh looks like damage from a coin rolling machine not the rimming process. The coins are delivered to chubb and arnaguard (although armaguard hardly do rolls anymore) loose and then these security companies roll the coins for redistribution. They can be pretty harsh sometimes. Report this Post to the Staff
The Unicorn Pillar of the Community Australia 750 Posts	Posted 11/09/2012 10:05 pm Thanks to all for their thoughts! Blasted rolling machines! First time I'd seen marks like this. It seemed so different to the normal obliteration of the legend with scratching that normally results. Alas, back to the pond little fishy ..... .... Report this Post to the Staff
