Had to see in the photos and almost that direct to see in hand but it’s there. Just not very pronounced so it must have been toward the beginning of minting. It’s a nice variety to have.
The reason some are not that visible is in part because of the hubbing process. It takes 7-10 blows with the hub to make a die, with the die being re-annealed between each blow. When you have a design hub doubled die like the 7/8 TF Morgans, this is due to an unfinished die from one hub being finished with a second hub. If the first hub wasn't used a lot, then it's part of the design will not be as pronounced.
