interesting relic, are there many of those in the area? Have those been found in any digs to determine a relative age?
I know very little as i had never heard of these until the night before the auction, when the seller, an expert on dakotas artifacts informed me that an odd piece I had found years ago was actually a top. I had brought it to show him, as after many years no one including two state archeologists Could tell me with certainty what is was. . And he informed me that they are very rare.
Since as it turned out I already had one of these specimens, I figured I might as well become a collector and went after this one offered on the sale. Judging from the bidding and where the price went, I can tell you, they must be sought after.
