Caveat: I have spent a while in Mainland China and I am not someone looking to splurge on souvenirs.
I went there and combed through nearly everything -- there are probably better places to find genuine antiques. I'm not convinced these are true antiques -- probably they're copies of antiques. Saw a lot of globe watches that look so identical and cost around 100-150HKD each. 80-100HKD seems to be the lower-limit price for most of the antiques here, even for things like one piece of old notes. You can also find things like old Chinese posters and even some old pornographic pictures. I thought they were just too expensive for the fact that some appeared to be copies and not genuine. Just my opinion, anyway.
Also, there is a lot of Chairman Mao memorabilia (which I wasn't enthusiastic about).
In my opinion, there's nothing much worth buying here, unless you find something very unique. If you do manage to find something unique, you'll have to pay at least 100HKD for it.
