Yankee Printing Plates. Help?

Not to start an argument, but I was told these things are not the real printing plates because a printing plates used to make a paper would look like a photo negative meaning it would all be reversed so it came out the right when when pressed against the paper. Right or wrong?

Wrong. The inked aluminum plate is pressed against a hard rubber roller, which creates a negative that is then transferred to the paper as a positive.

You can Watch You Tube for the process , the plates should have a registration number

The 1-of-1 printing plates inserted as chase cards have the image correctly, not reversed.

I picked these up last year at a yard sale. I'm guessing they are the same kind of thing.

You are correct, What you have are actual printing plates, most likely given or taken out of the printing plant, not many of each issue out there since they are washed and reused each day.

Some printing plate chase cards have the correct image and some have the reverse image. A quick eBay search will show several of both.
