I think that's an annealing machine on the far left. It would not belong in the same room as the presses, but it's relatively light. Some of the drawers also look like they were set up for the photographer.

This is the largest and most powerful coining press in the world, built for the San Francisco Mint by Morgan & Orr in 1873. It is currently located at the ANA Money Museum in Colorado Springs.

Great collection of pictures. Wondering if they are all taken in the same era...
