Collector's coins are a commodity rather than a 'paper' investment and as such supply and demand factors will affect prices. Historical price trends are clearly relevant too when any purchase is made with an eye to investment. It is recommended that these factors are researched either on the internet, reading numismatic literature, or appraisal from coin dealers, and periodic attendance at a major dedicated auction.
There are less obvious but in our view crucial additional and specific factors concerning firstly grade and authenticity, and secondly entry price which must be fully understood.
