Thanks for your help.

I just checked ebay - here is the only one I found at this time advertising doubling.

Great pics, coop.

Those are in circulation now?

I've written about this form of doubling many times in Coin World in 2002 and later in Numismatic News and the CONECA Errorscope. My original article on the topic covered the 1984-D Olympic dollar while later articles covered the 5 ounce silver and normal sized America The Beautiful coins.

So what does hub doubling look like on a doubled die? Here is an example from a 2013 cent:
Note first the raised devices that are doubled:







Now note what the incuse hub doubled deivces look like:



So the rule is: On devices that are raised, if they are enlarged on a coin from the die, it is hub doubling. (other conditions like coin contact can affect a single device, but the enlarging I am referring to is several of the devices)
On the raised devices if they are reduced in size, they are machine damaged/doubled.

On incuse devices the logic is reverse because of the devices being raised on the die. (instead of incuse like the raised devices would be). The die movement enlarges these devices and the hub doubled incuse devices are reduced in size.

So just as the difference in raised and incuse devices are opposite of each other, the doubling by hubs and machine damage (doubled) are just opposite. Confusing enough? LOL
