Thanks for your review!

Clunky

This app does what it’s supposed to but using it needs improvement. The search feature is terrible. I ran a search for “0.25 eagle” and it returned zero results. Then tried again and it came back with only two results, both were for half ounce coins. Trying to find the most basic coins is a chore so after over a year of paying for this app, I’m leaving and will verify my gold and silver purchases through alternative means.

Response from developer

Hello, We are sorry to hear that. Would you like to try "Gold eagle" directly as keyword? The app has a huge database and the search sometimes cannot find the optimum results. Please feel free to reach out to us by email, we are happy to help on any concerns on the app. We will also work on reducing the difficulty in the coin search. Best regards, Precious Coin Tester team

Without this tool, I would have accepted over $1,000 in bogus Morgans and Silver Ridge coins.
More than pays for itself on a daily basis.
