I have to say that I am pretty suspicious of the authenticity of this neck collar. I see signs of it being authentic and other signs that make me wonder. I say this acknoledging that I am no expert on authentic items from the period. The selling price tells me that there are those who know for sure what this is and that it is authentic.
