A Study of the Trade Dollar Type 2 IIM Reverse

stealer

Fair warning: this is another boring Trade Dollar research thread.

There are two designs exhibited in the Type 2 IIM reverse. Whether this change was in the master hub/die or working hub/die I have no idea and one would have to ask
those better versed in the die making process. I will call them D1 and D2. D1, from what I have observed, is far more common than D2. Pictures will be posted in the order
of D1 and D2 from left to right respectively. All pictures owned by HA or PCGS, none of these coins are in my possession. Links to the coins used in this study can be found below.

Hair Detail: Note the differences in the feathers coming off of the eagle's head.


Note the variance of the hair highlighted here. There are other minute differences but this seems to be the most obvious.



Beak/Face Detail: Note the stark difference in eye shape. D1 is far more oblong and D2 is more circular. Also note the beak differences:
the top part of the beak in D1 runs all the way down past the bottom part of the beak whereas in D2 the top part of the beak ends halfway down the bottom beak.



Leg Feather Detail: Note the difference in the feathers surrounding the leg. D2 clearly exhibits more finely carved feathers.


Leg Fold Detail: This is the first difference I noticed. Note how the top leg fold in D1 is curved upwards on the left side whereas the top leg fold in D2 is relatively horizontal.
This detail is harder to see when the coin is weakly struck. Also note how in D1 there is an extra leg fold between the lowest feather and the highest part of the leg. This
split is not seen in D2.

Excellent work

Thanks TDN, it was posted for the nearly non-existent crowd

On another note, your 77CC is the only D2 example that I have been able to find so far of the date/mm.

Very nice.
I see a difference between D1 and D2 which might be slightly easier to describe.
In the area where the neck meets the back of the head:
D1: Neck makes an unnatural edge which drops below head level to create a "V gap"
D2: Neck does not make angle to gap, but head rises abruptly above neck

Illustrated with the images you have presented.

Interesting.... will have to do some detail checking on my TD's....Cheers, RickO

Realone's pic is a little small - not sure I can see the details.

Yosclimber, you will have to PM me further visuals because I am a blind bat and can't seem to pick up what you're seeing there

Realone, nice D2! They're really not common at all. So far I've only observed them on the 77CC and 77S.

It should be noted that TDNs 77cc is a RPM (one of if the strongest of the series)

Good digging stealer but I am not sure some of that isn't simply strike variances during both the coin striking phase or the die creation

Crypto, thanks for the check. I can certainly see the variance in hair detail being part of the die creation variation.
