Why do you need an appointment?

Glad you asked, we schedule appointments for your privacy and safety! Criminals are becoming more daring when it comes to robberies. Stores with open doors and no appointment policies expose you to criminals who can be watching for people with valuables to be followed and robbed as you get home. We have even heard of some unscrupulous minimum wage workers setting up customers with high value items to be robbed. Your life isn’t worth the risk. Markham Numismatic has been in business for 38 years, we are a Better Business Bureau Accredited PCGS Coin Appraiser . So to provide the best service to our clients we are by appointment Only!

We are Preferred by Attorneys, Courts and Trusts! We work with people who have coin collections that they would like liquidated. We give customers liquidity for Rare Coins and Larger Coin Collections. PCGS & NGC Coins .We evaluate collections at no charge, with purchase of the coin collections of value. If we don’t purchase your coins, than a minimum evaluation fee of $250 would understandably apply. We also provide expert coin appraisals which start at $250.00 for a simply summary appraisal . date of death appraisals, probate appraisals , estate appraisals are based on scope of work and time needed.  If we end up purchasing  coins of value part or all of the appraisal fee can be refunded.  please email us questions and you can set an appointment .
