I would give the benefit of the doubt if the roll was high enough for Ashley but you'd have needed to cast guidance on her.
What I do for stealth is only count the lowest score and what I do for perception is count the highest perception score in the room including any bonuses for smell or hearing etc but you only get one roll.
In the future, consider saying something like "let's try to investigate this" and delegate it to whoever has the best chance. It's a cantrip so I applied it to Ashley and added her bonus instead of yours but these still don't offer much more information. I'll add a line.
Ashley takes one and feels it in her hand. "The cloaks are just wool, but these brooches maybe silver? They're definitely magic and they look elvish to me. I hope they're worth something. "
