I think you mean the 1972 Munich Olympic 10 Mark commemoratives. Those were sold in boxed sets and today bring close to their face value (about $7/each) as that usually exceeds the value of the silver content of .2250 troy ounces. There were no Olympic 5 Mark commemoratives but there are plenty of 5 mark commemoratives of various dates both in silver and copper nickel honoring famous Germans, museums and universities. Most of these range in price from face value to $20 depending on the issue and whether it is a proof or business strike.
