I love the wiki concept on a whole community working on document together that could be used on the long-term. These documents may become the reference and authority on the subject for years to come. I've read for a while and not participate a lot but I think it's time for the community to build something bigger and take the leadership role.
Wiki-list of coins composition and guide on each metal will be easy to print (survival mindset, working without computer if necessary) years of knowledge spread everywhere on the internet and in the forums, not so easy to print and easy to find instead of having to search in a thousand of forums post over many years. Let's build ourself a reference in coins composition, that we could use to sort and buy/sell foreign and even local coins for metal.
I would participate in wiki and help build guide to Canadian nickels and cooper for sure and use it to sort/trade foreign coins.
So ya or na ?
