Questions

Will I be charged during the free trial?

No. You add a card to start, but nothing is charged for 30 days. Cancel any time before then and you won't pay a penny.

Can I cancel anytime?

Yes. Manage or cancel your plan whenever you like from your account, and we'll email you a few days before a trial ends so it never renews by surprise.

What happens to my collection if I downgrade?

Nothing is deleted. Your collection and wishlist stay put; you just lose the paid features (like auction alerts and full price history) until you upgrade again.

Which plan has the auction alerts?

Collector and Pro. Add coins to your wishlist and we'll email you the moment a match comes up at auction across the houses we track.
