You can still exchange or donate (UNicef, Peta) all old European currencies (e.g. deutsche marks, austrian schilling, etc.) through the related link.
No, you cannot trade in Deutsche Marks (DM) in the U.S. The Deutsche Mark was replaced by the Euro in 2002, and the DM is no longer a valid currency. However, you may still be able to exchange Deutsche Marks at some banks or currency exchange services, but this is typically limited and may involve fees.
The official exchange of Deutsche marks has come to an end. However, you can still take your old German currency to the Bundesbank (Germany's Central Bank) and exchange it for euros. Most currency exchanges (banks, airport exchanges, etc.) will only buy currency that is still in general circulation. Specialized currency exchanges such as Euro Coin Exchange (http://www.webuyeuros.com/germany) will buy your old marks, and you can get paid in dollars without having to ship your cash to Europe.
Deutsche Mark bills and coins can no longer be used in ordinary commerce, but they can be exchanged for euros through the Bundesbank. As of 2016 the are no time limits or other restrictions on converting old D-Marks.

Deutsche Mark coins and bills can no longer be used in ordinary commerce, but as of 2016 the Bundesbank maintains its policy of exchanging DM bills and coins for euros without restriction.

No, the Mark ceased to be legal tender in 2002.
It was 5 Euro at the time of conversion. You might still get that for it if you exchange it.
I don't know if there's a way to directly exchange to USD, but the Deutsches Bundesbank should exchange to EUR. (see link below) www.euromoney24.com - here you can exchange your leftover former European currencies like Deutsche Mark, Franc, Schilling or donate it directly. Worldwide service, safely and comfortably.
Duetsch Marks I believe are still valuable. I think they would hold value just because of the fact they are from 1928.
At the time Italy converted from lira to the euro, the interchange rate was L1,936 = €1.00, so if it were still possible to exchange lira for euros that amount would be worth all of one euro cent.
IF you are fortunate enough to be in one of the countries that used to use the particular denomination, some large banks may still exchange them for euros (note - not " euro's ") However you may or may not take a beating on the exchange rate because there is no use for these old coins.
No, you cannot trade Italian lire for euros, as the Italian lira was officially replaced by the euro in 2002. The conversion of lire to euros is no longer possible through banks or currency exchanges. However, you can still exchange lira at the Bank of Italy for a limited time, but this service is subject to specific conditions and may have deadlines.
