CoinStackup is a tool for logging a coin collection, seeing estimated values, and connecting with other collectors. It is free right now.

Your account

You must be 13 or older. Keep your password to yourself. Don't pretend to be someone else.

You own your entries and photos. You grant us permission to store them and to show what you marked public. You can make a collection private.

Greysheet / CPG numbers are estimates, not an appraisal and not an offer to buy. We are not a dealer, escrow, or marketplace.

Any trade you make is between you and the other collector. We don't take a cut and we don't guarantee the other person.

No spam, scams, or stolen-coin listings. We can close an account that breaks this.

We may change or pause features. Data lives on our host (Railway). Back up anything you can't afford to lose.
