I think a US quarter fills the frame from top to bottom at 1:1 with full frame.

Thanks. What do you mean with this last sentence?

A US quarter is about the same diameter as the full frame sensor is tall.

If you took a close-up of a dinner plate with a US quarter in the center, at 1:1, only the coin would be in the frame.

When you fill the frame with the dinner plate, it's a close-up, but 1:1 is macro, where the coin fills the frame. That's the 1:1 you'll get with full frame.

You're using a full frame camera, so it doesn't matter what somebody else gets. You asked what you'll get at 1:1.
