The General Trend is to lower the limits frequently:
In either Switzerland or Liechtenstein, a cash value of up to a limit of 15,000 Swiss francs can be converted to
gold coins or silver bars via the so-called over the counter service. By the end of 2019, the upper limit allowed was CHF 25,000. This means that the cash limit for buying
precious metals is significantly higher than in other European countries. In Germany, the upper limit for anonymous shopping was reduced from 10,000 to 2,000 euros as of January 1st, 2020. With this value, the German
federal government exceeded the requirements laid out in the new
Anti-Money Laundering Act.
