Thomas Hardy Ale was designed to sit in the bottle for a long time, if stored in a cool, dark place. It's not that rare, but they stopped brewing it in 1998, so it is decreasing in availability.

A 1975 bottle in poor condition (oxidised, yellowed label) sold in November 2004 for $25, that appears to be cheap compared with This link where 'stupid' seems to be the going rate.

We have a couple of bottles lurking in our cellar somewhere..... maybe now is the time to check it out.....
