Get Too Much Gold To carry before or On Day 6.*
*Means you need to drop a coin before day 7,
but without pressing the coin drop button.
You can do this by being unlucky (a coin can bounce out of your gold pouch if it hits the side weird when it gets dropped in) or by bouncing off of other gold in your pouch (far more likely).
This can not be done in the same playthrough as "By the Eigth Day I Fumbled".
GL!
