How much is the gold spread between sale and buy back price?

If I remember correctly it is about 0,5%

For example gold shops sell the bars at 22 000 and buy it back around 21 900.

Do the shops apply any additional charges on top of this (if just purchasing a small bar, no jewelry)?

1% is average apparently....read this.....

Thanks for your reply.

I've read that, but the spread seems to be only 100 baht in most gold shops, so it should be only 0,5% or even less with today's high prices.

What are the best ways to make sure that the gold is real 96,5% thai gold, and not less?

The page suggested taking it to the laboratory, but that is a little too slow process and inconvinient and trouble some if the gold in reality isn't what is supposed to be , claims etc.

When I sell gold back,I take it to the same shop I bought it at.I take the sales slip with me.That way they know they're buying back the same percentage of gold they sold me.It works for me.

If you buy and sell through the major gold trading houses, then yes, the spread really is only 100 baht.

If you walk into any random retail gold shop, they will generally try and charge you 200 baht over the retail price when you buy a bar, and sometimes short you if you are trying to sell back as well. Generally when this happens, all the shops in the area are doing the same thing, so your only choice is to try a different part of town.

Stick with the brand name investment houses if you want to avoid this issue.

i think,that you can arrange lab on your own table;

you need :

-precision glass vessel to measure water volume,

-precision scale - digital scales are cheap nowadays and very accurate.

then you apply Archimedes law.
