Not entirely sure. If you hop on their discord perhaps one of the admins?

Shared mount collecting struggles 💚

I forgot all about that quest until after I bought the mount 😅

It took me several hours to run around and grab all the coins. I'd recommend doing the EK+Kalimdor ones, the Dragon Isles and TWW ones, and if you still need more then head to Northrend. There's a bunch of Northrend elders in dungeons, but that easily adds another hour.

I accidentally skipped an earlier post today but I made sure to cross-post this time lol

Congrats! I remember hunting down those three and getting absolutely zero cages for the longest time, and not even those legion medallions either, just Oil. Super depressing grind. Keep up the good work!
