Yes, we had to pay € 2.75. It was more of a souvenir rather an official stamp. Our cousin drove us to Vaduz, Liechtenstein, it is near St. Florin Cathedral and their main post office. You can take a train from Zurich, then a bus to take you near the post office. You can google the exact details.
@luisdiegohidalgo, That risk exists depending on who will strictly impose the rules. However, the risk may be lower than getting a stamp from a tourist location instead of a real country. If you think about it, Liechtenstein is a bonafide state; if not for the Schengen area, our passports may have been stamped if we enter the country. We intend to get stamps from other European microstates like San Marino, Andorra, etc. What we won't do is get stamps from non-state tourist spots, e.g., Checkpoint Charlie. We have been back to Europe and traveled to Asia several times and have been fine so far.
Hi. Did you have to pay? was it easy to find the office?

Is there a risk of invalidating the passport?
