1796 Castorland Half Dollar US Colonial Impaired Proof - Help Needed

It may help to take a transverse cross sectional photo to determine if it is a cast coin with a seam etc. Usually that's indicative of it being a fake.

The Casterland medals were propaganda pieces to promote a proposed French colony in Casterland New York. They were a medal or Jeton not a coin. The silver originals were distributed to the board members overseeing the colony. The medals come as originals and restrikes with the restrikes being made in copper silver and gold. The originals all had reeded edges the restrikes come withe both plain or reeded edges. The official restrikes will have the metal composition marked on the edge in French ("Argent" for silver or "Cuivre" for copper) the marking is almost always on the edge below the beaver. There have also been unofficial restrike/copies made. I suspect this is one of the modern unofficial copies. One reason being that the details are even sharper and bolder than on the originals.

You all have been super helpful.

#1 Not cast.
#2 Not filled with lead.
#3 Neodymium rare earth magnets are awesome. Thank you for telling me about them and I had to buy some ASAP.
#4 Smooth edge.
#5 Engraved on edge is what appears to be a stylized outline of a motor vehicle followed by the letters "BR". The "B" may be a "D" but I am pretty sure it is a "B".

Getting very close now to solving this mystery. What significance would "Impaired Proof" carry with it as well?

Thank you all again very much and I appreciate all the assistance.

Must be from a time traveler if there is a motor vehicle on the edge. My guess is its a fantasy piece perhaps for a souvenir shop.
