Those of you who have followed the detail of 10 Pound Bag closely will note that the amount of gold Zach has on hand has changed.
This is part of the rewrite process as I've learned more about the economics and micro-economics of the time. As the author and because this is fiction I've decided that Zach could take up to 10% of his liquid assets in delivered ores; limited only by weight.
I'll write a full blog post on the actual meaning of this over on my Patreon page but basically delivered for stocks or commodities means that you actually hold the certificate or item in hand as opposed to it being kept at a Holding corporation (Yes such things exist for investments).
Sorry for the in process change but this is my first attempt and I'm learning a lot as I go.
