If it went for 8 BTC it was still a pretty good deal to the buyer in my opinion, that's barely over Bitcoin + Gold spot prices at the moment.
Current Prices (from Amagi): Gold: $1275 Oz. Bitcoin: $222
$1275 1 Oz. Gold / $222 = 5.74 BTC + 2 loaded Bitcoins = 7.74 BTC total spot value
So all in all, that was a steal on a Casascius premium and the premium for the low mintage Titan One Gold.
Well, since the auction ended while bitcoin was at $241 and Gold at $1281
I saw the spot on the coins at price: 5.135 + 2 = 7.135 (and premium)
At the actual time I made my bid, bitcoin was at $281 which means the value in coin was less than the auction ending price.
I was going to bid 7.5 ending, but since he went to 8btc, I gave up.
Congrats on the sale. Next step is to make it complete.
