NumisMaverick is my personal coin-collecting project—a place to share practical calculators, numismatic research, collection notes, and the lessons I pick up along the way. Everything here is built from a collector's point of view and shared for fellow students of the hobby.
Personal collector—not a coin dealer.
NumisMaverick does not buy or sell coins, broker transactions, accept consignments,
or provide appraisal, grading, investment, or financial-advisory services.

Built around history, character, and the hunt.
I collect coins because every piece sits at the intersection of history, economics, design, and human behavior. My interests are intentionally broad, but I keep returning to coins with something to study: an old holder, a recognized variety, an unusual grade, a strong original look, or a story worth documenting.
This site is the public notebook for that pursuit. Collection posts are shared for education and hobby discussion. Coins shown here are part of a personal collection or collecting journey and are not offered for sale.

About NumisMaverick
A collector's notebook, made public.
NumisMaverick is the personal numismatic project of Timothy Roache. It began as a way to document coins and developed into a growing library of calculators, reference pages, market observations, and lessons from the collecting journey.
I am a member of the American Numismatic Association and serve as Secretary of the West Hernando Coin Club. Those affiliations reflect participation in the hobby and numismatic community; they are not commercial endorsements.
The goal is simple: study carefully, share what I learn, and leave behind resources that make the hobby easier to understand and more enjoyable to explore.
