Here are the remaining three that are going up for auction next week. I'd be surprised if we didn't find die matches among these types - it was a very limited run in a very limited locale. Sometimes these coins have eagle countermarks, which is Howgego 340. The eagle is facing right, stooping down, his head to the ground and his wings lifted up slightly behind him. I find that interesting - was there some symbolic importance to having the eagle in that posture?
The middle coin in your photos demonstrates that the flans used for these coins were cast en chapelet, that is, using molds in which a number of hollows were connected by channels. The sprue that connected the flans were sometimes not completely removed or, as in the case of this coin, chunks of the flan were broken off in the course of removing the sprue.
I bought number 7 from John's auction. I think this type is a fascinating coin, with a great reverse. I also posted it on a Facebook ancient coin group I am a member of and it received 32 likes, pretty cool!
