Built for

Stackers and collectors.

SevenOneFive is for silver stackers, coin collectors, and anyone who owns pre-1965 U.S. 90% silver coins (or foreign silver) and wants a fast, accurate melt-value tool that also tracks their holdings.

Hobbyist-friendly, not a trading platform. A calculator and a ledger, done properly.

How it works

Three steps to a number.

1

Set the spot price.

Fetched live automatically, or enter today's price yourself.

2

Pick a country and coin.

From Roosevelt dimes to Walking Liberty halves. Foreign coins too.

3

Calculate and track.

By count, face value, or full bags. Add it to your ledger.

Features

Precise where it matters.
Beautiful everywhere else.

Instant Melt Values

Enter the silver spot price, pick a coin, and see its melt value by count, face value, or full bags. Every figure — melt value, per-coin value, pure silver ounces, total face — updates as you type.

Track Your Stack

Build your collection. Add coins or whole bags as separate line items and watch your total melt value, pure silver ounces, and face value update live.

Multiple Countries

U.S. dimes, quarters, halves, war nickels, and silver dollars, plus Canada, Great Britain, Australia, and Mexico. Each with the right silver purity and year ranges.

Live Spot Price

Fetch the current silver spot price automatically, or enter it manually if you'd rather work from your own number. The app reminds you if a manual price has gone stale.

A Dozen Themes

Hand-crafted themes turn the app into anything from an engraved silver certificate to a waving flag to a 1980s green-screen terminal. Pick the look that fits your collection.

Private by Design

No account. No login. No data harvesting. Your ledger lives on your device — not on someone else's server.

"No account. No tracking. Your data stays on your device."
