Collect UK or US Coins?

Numismatics or coin collecting is becoming very popular especially with the surging price of gold, silver and other metals as well as the surging growth of the collectible industry. It's a well known fact that UK and US coins are two of the most popular coins in the world because of their global distribution and history. But our time and capital is limited. Do we buy UK or US coins or both? Both have their own strengths but as this book would explain, one is clearly better than the other. This book would also detail the world of numismatics with its own powerhouses and why this is so. Hopefully after reading this book you would have gained some knowledge which would be of help to your career or business especially if you are into numismatics... My pen name is Russel Ison. I write about novels which I think people would like but I especially like. I am semi-retired and spend most of my time researching all sorts of subjects. From Science, History, Mythology, Crime, Music, Movies, Saving Money, Romantic Comedies, my list goes on and on. I am however mainly interested in writing for people.
