No wonder. I looked up if either Nigeria or Lagos has any history of precious metals coinage. Not much except for a few commemorative issues back a while under Colonial days. At least having Crypto is a potential option by stacking the best cryptos. But if you have access to fertile land to grow food is the next best thing in my opinion. My small plot can only grow a limited variety of food in the warm part of the year.
I think Silversaver888 has a few left in stock if you are able to afford one. There is a link near the bottom of my post.
