Chad, please don't feel that people are jumping down your throat on this--remember that no-one is questioning your motives or honesty on this. But those of us who remember the flood (and that is the right word) of restrike/fake badges that came out of England in the 1970s have cause to be concerned; I remember being offered a magnificent Guards Machine-Gun Battalion officer's sterling silver badge in about 1976 in London--without any hallmarks (which was illegal, actually!). Fifty pounds. I didn't buy it, as I was fifteen years old and fifty quid was simply more than I could afford (I did get a Newfoundland Forestry Battalion badge at a junk store on the same trip for fifty pence,though!
Question for you: who owns the dies/moulds for your repro'd Seaforth badges? Did you buy them from the casting house? Did you destroy them? What will happen to them if they're not in your possession, or after you die? Things like that tend to get used, sooner or later; and I'll bet dollars to doughnuts that if the dies/moulds float around long enough, someone will start to cast up "Piper's" badges in silver, or 9kt gold "Commanding Officer's" issues, or some such nonsense.
Also, what happens 50 years from now when we're all gone, and your repro badges have a patina of age on them? It will be pretty much impossible to tell a 50-year old repro from a 120-year old original by that point--and that's without factoring in those who deliberately age things artificially.
Once upon a time, most of the Canadian repros/restrikes/fakes were fairly easy to spot; wrong metal, or solid back casting, or wrong fasteners. But things have changed. The recent numbered artillery badge repros are really, really well done. Already several have been mistaken (or, sadly, deliberately passed off) for originals. Whatever the intention of the guys who made the repros were, they will be misrepresented by a small percentage of crooked people out there. It's just inevitable human nature. My feeling is, why make it easier by producting exact
copies--for display or re-enactment, it doesn't really matter what the reverse of the badge looks like.
Please give strong consideration to having the reverse of any further repros look totally unlike the originals--a solid, "satin" finish back, with your name and the date stamped (as deeply as possible!) would suffice. Besides, think of it as a legacy--maybe collectors in the 2100s will be paying big bucks for "original Chads!"
