Coinstar meets treasure hunting

Don’t just count your change — hunt for hidden treasure.

MintSifter is an AI‑assisted coin kiosk that scans jars of change for rare and collectible coins, turning everyday coin returns into a high‑margin treasure hunt for shoppers and host locations.

How MintSifter works

Feels as easy as a coin counter, but tuned for hidden collector value.

1

Deposit your change

Customers pour jars of coins into the kiosk just like a standard counting machine.

2

AI scans for treasure

The system analyzes dates, mint marks and patterns to flag coins with potential collector value.

3

Cash out and keep the finds

Users get normal cash payout plus a breakdown of any flagged “interesting” coins.

For stores, venues and properties

Turn a dusty corner into a high‑margin, high‑engagement experience.

  • Drives repeat visits with a “treasure hunt” hook instead of a boring coin dump.
  • New incremental revenue without tying up staff or floor space.
  • Flexible models: host fee, revenue share, or co‑branding.
  • Attracts collectors, hobbyists and curious families who love the reveal moment.

For investors

A familiar behavior, a bigger outcome: coin‑counter flows with collector upside.

The opportunity

Billions of dollars in loose change pass through counting machines every year. At the same time, the numismatic market pays premiums for specific dates, mint marks and conditions. Today, those worlds barely touch.

MintSifter sits between them – using AI‑assisted detection to surface potential collector coins at the moment of counting, and giving hosts a reason to install kiosks that feel more like an attraction than a utility.

  • Hardware + software recurring revenue model.
  • Hosted in grocery, mall, airport and casino footprints.
  • Upside from counting fees plus shared value on flagged coins.

What could be in your coin jar?

Example values only – actual collector prices depend on condition and demand.

Common quarter

Face value

$0.25

Most modern quarters are worth exactly what you expect.

1964 silver quarter

Example collector value

$5–$15

Pre‑1965 silver content alone can be many times face value.

Error or key‑date coin

Example collector value

$20–$200+

Visible errors or key dates can command serious premiums from collectors.

Frequently asked questions

No system can guarantee perfect detection. MintSifter is designed to assist in surfacing potential collector coins based on visible patterns and data, while still operating as a standard coin counting kiosk.

The kiosk highlights the coin as “interesting” and explains why. Hosts and operators can choose policies for payouts, upside sharing and whether the user keeps or sells the coin.

MintSifter is in the design and prototyping phase. We are lining up pilot locations and investor partners. This page is part of that early conversation.
