I have bought from them and a few others like JM Bullion, be ready to pay tax of about 16% for silver coins. Sometimes even bars also kena tax because they declare the wrong HS code or the custom officer will just tax because he is not sure.

I had to go the office in KLIA to settle the issue 

Out of 5 times, I normally kena 1 or 2 times. The other times which I do actually order silver coins, the courier (either UPS/DHL/Fedex) will call and ask you to settle the tax payment with them.

So long story short, I rather just get locally to save all the hassle because at the end it feels a little like 'penny wise, pound foolish'. This is a long term investment and your long terms gains would easily cover the extra premium you are paying now for the convenience. 

Bro,
Apmex fees is in USD.
MY n SG have just as reputable dealers.
If u wish to buy gold coins, try our Tiger Bank, etc.
If u have serious trust issues with MY banks n dealers, then buy from Bullionstar, Goldsilver in SG. Shipping fee is like SGD40, for 100 grams gold.
Surely, you can trust SG governance/regulations.
You gonna redeem yr bitcoin for lots of gold?

Tiger bank is Kijang Emas.
What we want is the gold bullion, 99.99%. I wud say highly recognized n easily transacted locally.
Dont buy coins, the premium % over spot is high. Preferably, 100 gram bars; or 1 oz coins (if its gotta be coins)
SG Bullionstar accepts bitcoin.
But why sell bitcoin now, when likely months away from market cycle top?
I collect boring Swiss Pamp n 24K jewellery with 0% workmanship (old design on sale)

Suggest that you consider buying Bitcoin instead. They call it Digital Gold...

Apart of taking it out occasionally to caress and admire its glittering,
why want to go through the hassle of buying physical gold, when you can own liquid asset tied to gold like GOLDETF ??

Actually, if above usd10k, must declare. Doesnt mean cannot take out of country.
No issue with cash, why carry so much, bank account need not declare.
Just declare in-out, n show proof of local purchase, u shud be ok.

Good to have some fears n scenario planning (what u doing now) vs a green horn.
My worry has always been the destination airport customs. ( i mean the corrupted ones).
Personally, i hand carried some large amounts of cash back to MY to make purchases, the biggest was SGD450K.
The MY Customs officer wanted to see the stack.

Bro, u seem like a well balannced guy, (head screwed correctly), most others are a like owning one or the other.
Good to diversify, u r doing right!
