"Three Coins in a Fuchsbau" received positive reviews. The A.V. Club's Kevin McFarland gave the episode a "B" grade and wrote, "This week threw a wrench into the typical procedural structure, using another tried-and-true option for supernatural shows: the magic object. In this case it's three gold coins, which benefit the holder with an extreme amount of confidence and bravado, but with the drawback that they make whoever touches them completely obsessed with obtaining them. I can think of many different shows that have used this different structure to brilliant effect — the Buffy bottle episode 'Older and Far Away' is probably my favorite kind-of-cheating example — but Grimm hasn't built up the kind of complicated relationships to pull something like that off. This is the kind of mystical element that everyone wants to have, not one that forces a new kind of situation. The same, stable steps through a case are the still there, just heightened a little bit by the presence of the coins."[3]

Nick McHatton from TV Fanatic, gave a 4.5 star rating out of 5, stating: "The bromance between Eddie and Nick brings most of the humor to the show and he's a much better partner than Hank. With all the attention he gave to the cameras in Nick's trailer, I kind of wished Nick had invited him back to watch the old film. I would have loved to get Eddie's take on Hitler being a creature."[4]

Shilo Adams from TV Overmind, stated: "'Three Coins in a Fuchsbau' was a tiny step back from the past few episodes in overall scope, but I think that it can be an important episode going forward. Nick hasn't really had to deal with his past much, once Marie, his last living relative, passed and it'll be interesting to see how he responds emotionally to Kolt's information. The fact that he included Juliette in the loop may indicate that Nick won't be ignoring the fact that his entire worldview got shook once he found out the role the Wesen world played in the death of his parents. He's seemed like a nice, normal guy from the beginning of the series and I root for him and Monroe to continue learning from one another and growing, but I felt like I barely knew Nick Burkhardt before 'Three Coins in a Fuchsbau'. The episode may not have provided a shocking reveal, but the fact that Grimm seems ready to embrace its true beginnings and bring on the mythology is a very, very promising thing for the show. Grimm may not be much on character backgrounds, but when it does fill in between the lines, I find that I'm liking it (and its characters) more and more."[5]
