Well, those coins have a face value of 8.68 DM - which is €4.44, or $5.88 (US) or 6.18 (AU) if you took or sent them to the Bundesbank. Don't know what a silver melter would give you for the 5 DM piece, but I am pretty darn sure that the scrap value is higher than that ...
In many countries around here it is perfectly normal that old coins lose their value as means of payment after a certain redemption period. In fact, of the 17 euro countries, only five have an unlimited redemption policy for both coins and notes (at least for those coins and notes that were legal tender until the euro cash introduction): Austria, Estonia, Germany, Ireland, Spain.
And since the end of such a redemption period hardly ever comes out of the blue but is usually announced well in advance, I don't see what the problem is. You may want to set some reminder in your calendars, e.g. 1 March 2022 - Portugal/notes or 1 January 2032 - Netherlands/notes. :)
