Meet Our Team

At Key Valuation Services, we keep things personal and professional.

You won’t find a call center or rotating staff here - just us: Jonathon and Jeannette. We bring many years of combined experience in valuation, estate services and client care.

Jonathon Tinkey - Founder & Lead Consultant. Jonathon was the kid who used to take two one dollar bills to the bank and ask for rolls of pennies so he could look for wheat pennies. He fell in love with numismatics attending a coin show with his grandad over 50 years ago. He has developed a keen eye for value and has facilitated private sales of gold and silver bullion for hundred’s of thousands of dollars. Jonathon works with private individuals, attorneys and trust officers to maximize the value of their collections.

Jeannette Tinkey - AKA Nancy Drew is a voracious researcher and super sleuth determined to uncover the secrets of any potential provenance for items put before her. When not consumed with research, she loves on our black lab, Bella, grown children and grands. If that’s not enough, you will find her puttering around in her fancy-schmancy office doing artsy-fartsy stuff like calligraphy.
