I don't see any hub doubling yet. The mark on the 2 on the upper edge of the lower cross bar is on the master die doubling. But all the devices appear to be the same size.

The rim Cud is cool though and nice to find on a mint coin. |

Thanks 7. Yes - for once the coin isn't beaten up. Hi Coop - I was thinking MDO and I read that their were 2 working hubs for the date. But I don't have either of the die gouges that they describe. Here's another shot of GOD - note the tops of the devices are thin but thicker at the bottom - perhaps die wear. But no notch in the D as with the Master Die Doubling or evidence in IGWT of that. Odd, but I set it aside for now for the Cud.  Edited by Rackster

Morning Kevin. I am not seeing a DDO and the rim Cud is a bit common @9 for the date. Keep if you like but I would not. John1  |

The reason the letters are tapered is not die wear, but die abrasion. The difference? The dies wear in the direction of the rim. On your coin the letters are thinner near the rim and normal at the bottoms of the devices away from the rim area. Because of clashes the dies get polished and on your coins die probably more than once. The devices can show a tapered look when they overwork the outside edge of the die (which your coin shows they did.)   Note how the devices get thinner next to the rim? On die wear they get larger/distorted:  So a deteriorated/worn die is a die aging process. Abrasion is a die clash removal with the dies fields first being affected and then the shallow devices and so on. Die wear is a natural wear on a die. Abrasion is man made wear to the fields of the die. |

Thanks for pointing out the distinction. Indeed this is a case where the device details by the rim indicate abrasion despite the absence of th typical lines and witness marks. Some tool men are gentler than others and perhaps more discrete about their efforts. This will be filed as a Cud. A question though: are you familiar with the two MDO working dies? Pictures of both side by side perhaps? I'm asking a lot here but curious what the 'second' working hub looks like. Thanks! |

The two working master dies are the MDD (Master Doubled Die) and the normal master die.

Thanks Coop. I was thinking that there were two different looks for MDO. My mistake.  Hi John - this was the first one that caught my eye. It might be that I focus too much on the IGWT. But I suppose I'll see it more now that I'm aware of it. |
