U mean buy? if so u can buy from warspear homepage, safest way ;)  u can only buy mcoins for real money, or trade the games currency to other ppl so they buy mcoins for u, not the safest way becuse u can get scammed :(

Hmm, in have no clue about the gold price  for mcoins, never buyed it so.... but a smart way to see, is to compare mcoin shop items gold prices and see how much u can sell it for, then u can get a budget over how much u can sell or buy mcoins for :)
EDIT: i would sell 3500 mcoins for 350k gold
