Very interesting topic. The expense of bunter fabrication pre-EDM has no doubt made for some of the many varieties of headstamps that add to the fun collectors have.
I have always considered this part of the game to be very nearly equated to numistmatic adventures as there is a very wide line when it comes to the functionality of a device’s application versus the perfection of its execution.
In better times, the typical coin or cartridge will have well struck and defined devices while, especially with coins, in harder times, quality takes a back seat to practical production standards. The example you show, while weak in detail, probably served to indicate what it was. Job done. Old U.S. coinage often showed major die cracks and huge flaws that detracted from the beauty of the object but really didn’t change it’s funtional capacity. Sadly, economics drive the ability of a manufacturer to make a “beautiful” product.
All that being said, let’s talk tech.!
Any idea how many hits an average bunter can make before it becomes unsatisfactory for typical commercial use? Assume the basic 70/30 brass and 20th century metallurgy and no other odd variables…
