Coin Appraiser Palm Desert, ca PCGS Coins & NGC Coins could see demand Drop next year !

Coin Collecting is a Dying Hobby !

We are seeing more and more old time collectors passing away.

Which bring more and more coins onto the market .  PCGS and NGC  have had the grading market to themselves for a long time.  gradeflation is a problem .   well there is a new Sheriff in town ..  and this sheriff has the power to shake things up!!!  if the market likes this new grading service it will make demand for PCGS and NGC graded coins go down.     time will tell what happens .  we are recommending our clients set up an evaluation appointment to assess the quality of there higher graded Rare coins .   


We are not seeing younger people collecting coins. This is a disheartening trend .  Covid sounds like it’s coming back, which can slow the economy and make the recession worse, that is stated to be on the horizon.!

That is why we are recommending that people liquidate higher value PCGS Coin and NGC coins and coin collections , gold ,silver. 

Please see our website for more information on our appraisal and liquidation services .  We serving all of southern California .

Markham Numismatics  Coin Appraiser       Date of Death Appraisals 

True experience and knowledge of the coin business is gathered slowly from seeing millions of coins, understanding how each mint and each year has different characteristics features and seeing counterfeits first hand. It is not something you learn overnight. It takes years of experience in the trade. I became an expert by working in the coin business since he was 16. At 19, I worked as a coin buyer for David Hall rare coins and later worked as a coin grader for Professional Coin Grading Service (PCGS) grading coins at the age of 21. Being an expert is not just a word but the knowledge gathered in a lifetime.
