.hk names have limited speculative vale for a number of reasons.
The population is less than 7M so there is a small domestic market.
HK has a high level of Internet sophistication. Many people in HK were grabbing great .coms long before they were worth big money.
The .hk extension has always been associated with small local companies -- in part because all the big guys grabbed their .coms a long time ago.
Until recently you could only register a .com.hk, and you had to be a HK company to do it. Owners of these have first rights to the .hk. If a local company wanted a .hk they got dibs on it years ago.
.hk names can be registered in Chinese characters. Regardless of what any hypemeisters may tell you, everyone in HK does not speak English. In fact a lot don't. For small local business a Chinese name is probably better than an English one. Combine that with my points above and things don't look too bright.
As a result, even though beer.hk is a great name I couldn't see anyone paying more than $500 for it. They'd probably just pay regfee for hkbeer.com.
I don't see much of a market for DIY in the sense of DIY, but if you hang on to it until a company called Dai Ip Yeung becomes successful and wasn't to prepare for an IPO they'd probably pay you a similar fee.
Same goes for hkd.hk. People don't say “HKD” like they say “dollar”, “pound”, “yen, etc. so the currency aspect of it isn't all that great.
Sushi is probably the best name of the lot. Despite the fact that it is beer, not sushi, that's the national dish of HK there are probably more sushi chains than there are of breweries and distributors. Might not be worth more but certainly an easier sale.
