Found this 2020 w privy with what appears to be doubling in the letters Marsh buildings Rockefeller. Any opinions I thought it was machine doubling but there appears to be true doubling

Difficult to make a conclusion due to the glare from the lighting... My first impression though, is machine doubling. Cheers, RickO
Mechanical doubling on incuse letters produces what looks like a doubled die. I suspect that's what is happening here.
