Jackson $ edge lettering Question

[Tuebits]

Hi again,

The attached photos taken of 2008 Jackson edge letters appear to have a separation between the primary mark and a secondary mark. The secondary mark is to the left of the primary, the other lettering on the edge seem unremarkable. I don't find them flat like machine doubling. but I don't know edge lettering doubles. What do you think of them?

It's possible there was some jitter in the edge lettering die or the wheel that propels the coin through the die.

Jackson $ edge W extra leg

That same role had a "W" with an extra leg. Caught my eye quickly. Take a look.

Since it is at a different angle than the arms of the W, I would think that it was damage to the edge lettering die or the wheel and not any type of doubling.

Personally, I find the edge lettering on these dollars to be intrigueing!

For example, on this Satin Finish coin, the lettering looks to be an outline of the actual lettering:



While on the coin below, deep inside each letter, it appears as if there is a raised line running along the center of each letter:



To me, it appears that two different "styles" of lettering are used. Or perhaps the lettering is implemented differently on the machine?

For example, if the top coin is a weak edge lettering (i.e. lightly impressed), that tells me that the die on the lettering machine possibly had "hollow-point" letters. That could be reinforced with the second coin in that a more heavy impression could possibly leave a raised line in the center of the letter.

But, that does not address the coin below:



which has simply a thin line depicting the letter.
