Buying gold coins, rates wary from one company to other

On occasion of dhanteras I want to buy gold coins, asked 2 jewellers, Muthoot gold finance & ICICI bank.

All are saying that they are selling 99.999% gold but the rates are varying a lot among them. The price variation is from 4000 to 6500/- per 20gms.

Why is it so when the jewelers are selling at actual days gold rates.

dated 1/11/10
20gms ICICI coin 46618/-
20gms Muthoot coin 44097/-
20gms local jewellers coin 40600/-

All says 24carat, Whats so special about ICICI?
Can you advise please.

Todays Gold rate is 20000/- for 99.99 so
for 20 gms ur gold coin should cost u 40000/- + making ( which can vary from jeweller to jeweller normally should not be greater than 500/- )
So approx u should be able to get gold coin at max 40500/- as of todays rate. without Tax.
Banks and co. are always costiler as they inclued taxes as well.

ok so how much is the tax on gold 12%-16%?
Do we have to need a bill necessary?

oh no not that high on taxes. Its around 1.5%. Bills not necessary if u know the jeweller personally

if its 1.5% then ICICI rates are way over the roof for same 20gms gold, will ask the bank itself as to why its so expensive than the market rates.
