Collecting is better with people who get it.
Connect with other collectors, see what they're adding, compare where you stand, send coins back and forth, and race each other to finish a set.
A feed of what your circle is stacking
Items added, coins listed, sets completed, anniversaries, all as they happen. React with an emoji, filter the feed to one person, or switch off the kinds of activity you don't care about. A weekly recap card summarizes what you missed.
Top Stackers
A leaderboard of your friends, toggleable between items, value and weight. Competitive, entirely optional, and a surprisingly effective reason to finally log that box in the closet.
Transfers that actually hand the coin over
Send an item to a friend and it moves between collections, with a record on both sides: direction, date, weight and status. A friend's profile shows what you've traded, sent, received and netted over the years.
Race your friends to finish a set
Pick a type set, name the contest, invite up to ten friends and race. Standings update as everyone's collection does, with progress bars, a leader hint and a contest activity timeline.
You choose what's visible
Your collection, wishlist and for-sale items each have their own visibility setting. Anything you keep private shows a friend a locked placeholder and nothing else, its value included.
