715 for iPhone and Android

The calculator on this site, plus the parts that only make sense on a phone you carry to the coin shop.

What the app adds

A ledger for your stack

Add coins and bullion as you buy them and the app keeps a running total — melt value, pure ounces, and count — updated against the current spot price. It also breaks the stack down by type and shows a daily balance over time.

A deal checker

Enter what someone is asking, or offering, and it tells you how far over or under melt that lands, per coin and for the whole lot. This is the part that earns its keep standing at a counter.

Bullion and custom pieces

Eagles, Maples, Britannias, Libertads, Krugerrands and more, plus a custom calculator for any bar or round by weight and purity.

Price

Free covers the automatically updating spot price and a five-item ledger. Premium is $3.99 a year and adds every theme and an unlimited ledger.
