Ha, it’s still my guess that it will fetch over $400… let’s see! 😄
I doubt there are any trolls involved in bidding. Some collectors will bid way more than you would think even if it just went unsold. We’ve seen this happen before, and I know who some of the collectors are that will bid high when they want something. The seller has a good reputation among collectors as well which I expect makes nervous bidders feel a lot more comfortable.
Best of luck though!
