What is the minimum reverse rotation NGC or NCS will Lable?

[Hobo Bob-migration]

Nice downhill reverse rotation, but NCS will not call it out on the label... To Small?

 

 

In Alan Herbert's book under III-N-3 Rotated Die Strike - 15 to 45 Degree (IWE)

 

Usual U.S. Mint tolerance is 7 degrees for each die, so rotations do not take on value below 15 degrees...

 

This is a +20 degrees?

It's really a minimal error, in that perspective. 40º or so and your talking very noticeable . Don't get me wrong, yours is noticeable, but unless it had other errors, there is little to no premium for this piece, even though it is a mint error.

I thought that anything above 15% rotation was notable.

[L1ncolnF4n]

Notable I suppose, but not really of high value unless it was accompanied by other errors or had more significant rotation.

[bsshog40]

Well the OP was only asking about notation of the rotation. I would think, unless it has to be requested when the coin is being graded, that anything over 15% would be notated on the slab. There was no question about value.

[bartlesvilleok]

I have NGC and NCS that is between 170 to 180 degrees and neither of them are noted on the slab either

[L1ncolnF4n]

You have to tell them to mark it as far as I know...

[coinman1794]

It also depends on the type of coin. Early US coins often have large rotations and are usually not listed.

[Hobo Bob-migration]

Sent in as a mint error and 20 degrees rotation was requested. I even call them on this one... I guess Alan Herbert is wrong and according to NGC/NCS it's not a error...

It’s not that Alan’s wrong, 20º rotation is outside of mint acceptance. The issue at hand is that in the collector marketplace, it is not the level of misalignment that error collectors look for, and IMO actually detracts from a coin’s appeal (not eye appeal mind you) if it was not already being sold as an error for some other reason. My guess is this is what NGC has in mind. You should get it marked on the holder if you requested it, as it is true. For error collectors, we generally look for 40º-180º rotations, with +/- 90º being prime (as it is really unordinary).

I've been collecting mint errors since 1961. The minimum is 15 degrees but NGC calls it there way. Thanks for the info...
