There are three very similar pieces D&H 179, 180, and 181. The 181 came first. It was engraved by Droz (about the only work Matthew Bouton was ever able to actually get out of the engraver) and was the first piece produced by Boulton and steam powered coinage. Next came D&H 180 where the Droz obv was replaced by one created using Droz's bust punch of King George III but the rest may not have been done by him. Finally came D&H 179 where the reverse die was changed, the new die having the serpent arranged differently so that it's body passed behind the middle leg of the tripod instead of in front of it.
They made a lot of these medals as the King's return to health was a cause for great celebration. The 179 and 180 come struck in copper or silver. According to D&H the 181 was struck in copper, silver or white metal. They do not list the Barton's metal composition. As Catbert says the Barton's metal pieces are supposed to be very rare but I am beginning to suspect that many of the pieces listed as silver may actually be Barton's Metal. My 181 is Barton's metal, Catbert's is Barton's metal, I have seen at least one other listed as Barton's metal, and I have seen at least one piece listed as silver that was actually Barton's metal.
