Hello. Can you give some more information? When you noticed changes in gold? When you definitely saw what gold is ok? What unusual (like engraving, unbounding, trade with unbound, etc) you could do in that time?
I've noticed the difference today. On 7/9/2014 i bought 2000 Gold + 600 Bonus. New stand 27xx Gold and today 2314 Gold. I buy nothing at this time, no engraving or other thinks.
