Collector Coins lists every currency that buys a mount, pet, toy or housing decor you don't have yet, for all expansions:

• Gold of all your characters plus the Warband bank, for collectibles sold for gold.
• Currency totals for the whole Warband (account-wide, transferable with the transfer tax applied, and per-character ones shown apart).
• Currencies that are bag items are counted too (bags, bank, Warband bank and your alts' bags).
• Grouped by expansion, with each vendor and how many things you are still missing from them.
• Filter by Mounts, Pets, Toys or Decor to see if you can buy all of that type, ignoring the rest.

Type /ccoins or use the addon compartment button.

• Vendors and prices for every expansion come from AllTheThings (MIT license), extracted for each release. ATT does not need to be installed.
• Mounts, pets and decor are also read from the game's own collection journals, which Blizzard updates every patch.
• Every time you open a vendor, the addon learns what collectibles it sells and their exact price (fixes prices that changed).

Log in with each alt once so their bags are counted.

Collector Coins would not know half of the vendors without AllTheThings. Its team and contributors keep a huge, hand-curated database of everything you can collect in World of Warcraft, and share it under the MIT license. Many thanks to all of them!

If you enjoy collecting, please download AllTheThings on CurseForge too and support their work: it tracks every mount, pet, toy, transmog, achievement and much more, with where and how to get them.
