I think a problem here may be targeting. Many people who are knowledgeable about coins care very little for the packaging. The real limit to getting a coin into real circulation is getting to the knowledgeable people first. They inform other people and get the idea out there because it interests them. There is no simple package to shine up like a phone. There is a UI to shine up but that won't be enough to sell knowledgeable people on your product. Once it has gained a moderate audience it can be the thing that drives it to the more uninformed users but there is no easy channel to get it to them. Companies like Apple already had products and funds available. They were going to make more products anyways, they just made those products better and gave it a unified brand name (iPhone, iPad, iCloud, ect.). You have no existing channels of distribution or income in this field. That is a very large barrier to overcome. When Apple started it was because they had a unique, competitively priced product to ride on (Apple I). I also agree that you should try to start at another product that already has a following to try and overcome these problems or find a way to overcome these barriers to beginning your product.
