There must be hundreds of them in HK - big chains like Chow Tai Fook, Lukfook and down to what looks like little mom & pop gold shops. They will have a monitor in the shop that shows the gold spread (quoted per tael, not ounces).
I visited some of them recently with a 1oz gold coin in my pocket. All of them were interested in buying.
Many of them are clearly not used to foreign coins - even fairly common ones from national mints - they just see a nugget of gold and then are not sure what the purity is.
It got weighed, looked at under a loupe, passed to the old guy in the corner. The woman in KingFook spun it on the table and from the sound announced "this not 24K". She wanted to cut it and do a chemical test on it before giving me a price. I don't recommend KingFook - but attached photo is from there.
Along King's Road, NP I was quoted $800 below spot. I eventually sold if for $200 below spot at LC.That is my favourite gold shop - but my worry is they will be gone one day.
I'm curious if anyone else has tried selling to the jewellery shops - which one is your favourite?
