Shit no, far too small. Even the 1/4oz coins I have I think are too small, hence wanting larger size.
larger size .... sovereigns, olympic coins or 1/2 oz. But be warned at 1/2 oz ... liquidity not so good.
gold sovereigns and half sovereigns are good though some go for way over spot because of their numismatic value, ive been able to buy them on ebay for under $440 and under $220 for halfies they are 91.67% gold and a full sovereign's pure gold content weighs 0.2354 oz
