So blast from past - actual bug.
I would say so - though generally Antique Coins are substitutions for blueprints/decor(?) you already own, so you may possibly own them already by purchasing from the Antique Shop previously somehow and that's why the Coin substitutions are occurring. I'll query QA though for a follow-up about that.
edit: I've also alerted QA to the string issues regarding the pack names.
Market is not a bug, but a deliberate feature.
There's a bit of confusion in here regarding the ongoing market kerfuffle.
Originally there were a handful of issues involving the market that made filtering and navigating it unreasonably difficult. Up until this point players could both see prices and sell items of a higher tier they didn't have market buy access for. From now on when I say 'higher tier(s)', I mean items a player normally wouldn't be able to purchase due to insufficient merchant level.
After fixing the filtering issues, players were still able to sell these higher tier items but oddly they couldn't view the current prices they were going for, which made it a tedious endeavor to price it appropriately by having other players tell you the going price.
The most recent update however exacerbated this bug and made it so you couldn't see pricing information -or- sell higher tier items. The bug has been identified and a fix is planned for a future update - as for when, no ETA at this moment. To be clear, this fix will once again allow players to see pricing information for and sell items that exceed their accessibility tier on the market.
If you have any observations related to the on-going market issue, please use this bug thread to to keep the information consolidated for QA: https://discord.com/channels/482292231290617866/1341723357770416128
By my response, I assume they will shut this thread down - Kabam doesn't like me.
