Bill: I dont have access to a punch press. So, when I am finished using the embossing machine I use metal shears and cut the strip straight across.
If you have an arbor press, a large vise, or a small hydraulic press you can easily punch the shape of your tag with a pancake die.
You can either order the pancake die online or you can make your own in your shop using a fine cutting scroll saw or a jeweler's saw to cut the desired pattern on a hardenable sheet metal.
Sandwich your stock material in the die and press flat with a vise or a similar press to shear the desired pattern
The process works best on thin soft metals like the one you are working with. The quality of your result would highly depend on how good or smooth you shape the cutting edges of your pattern die.
Watch this video and form some idea on how to apply it to your own project.

Our dies use either 4340 or A2. You can use hard rubber or cork to push the material back out the lower die once you acquire snap through. If you have a place with a wire edm, they can make the dies razor sharp and then you surface grind them when they get dull. Tim
I make numbered brass tags which I sell to antique auto enthusiasts. These were used in the 1940's, 50's and 60's to identify cars built in England. These are made with an antique embossing machine. The brass stock that I have been buying is cartridge brass and comes to me in strips that are .875 wide and 36 inches long and .016 thick. The finished tags are usually 3 - 3.5 inches long and the strip stock is .875 wide. I need to devise something to trim the ends of the brass tags to produce a neat, near perfect radius. Or, in other words I want to round off the ends to a perfect semi-circle. I've been thinking about this for some time and I guess I would need some sort of trimming die with a semicircular profile. So, I think I know what I need. Now, I need some help to make it.
Maybe you have a suggestion!
Thanks, Frank
p.s.
This is what the tags look like out of the machine, including equally spaced mounting holes. However, as you can see, the ends are not quite round.

Are you wanting something you can take with you to the shows? How many tags would you need to make before breaking even? Project budget? I still like your tag project. The Very Best to You
