If Miguel has been collecting 5 coins each week and now has 38 coins, then he has collected 38-5=<<38-5=33>>33 coins since they started.
If Grace has been collecting 3 coins each week and now has 24 coins, then she has collected 24-3=<<24-3=21>>21 coins since they started.
Together, they have 33+21=<<33+21=54>>54 rare coins when they started collecting. Answer: \boxed{54}.
