Looks to me as though big block prices are falling. 3301 sold in 2007 for $935,000. One year later, it was bid to $775, 500, then in 2009, it was bid to $600,000. No sale on those but remember, it's only worth what someone will pay for it.
A few months ago, it sold at auction for $550,000 before commission.
It's only one 427 but I think the market for 427's has seen it top. I've always felt that 289's were a little under valued compared to 427's. But again, they are only worth what someone will pay.
