It's an ordinary circulation coin that was used up till Germany switched to euros in 2002.
At the exchange rate in effect at the time, 10 pfennigs (note spelling) were worth about a nickel.

"Deutschland" is German for "Germany". It's not a denomination. You need to look for a value indicator, like "pfennig" or "groschen" or "mark" or "Euro" or something to figure out how much it's worth.
It is worth nothing. The Germans no long use the mark, but are on the Euro. When it was used a 50 pfennig was about 5 cents. One pfennig was a penny.
This coin is no longer in circulation, having been replaced by euro-cent coins in 2002. At the exchange rate in effect at the time, it was worth about a nickel.
There is a website called Numista that has coin pictures. Also on eBay and so on ...
This coin was part of the old Deutschmark and pfennig system that was used prior to the introduction of the euro in 2002. At the time the exchange rate was roughly 1 DM = 50¢ U.S. There were 100 pfennige* to the mark, so your coin is, I'm sorry to say, only worth one-half of a U.S. cent. (*) "Pfennige" is the plural of "pfennig". The word is the source of our "penny".
One pfennig was to the German mark the way one cent is to the dollar. It's a common coin, worth maybe 10 cents.
Unless it's uncirculated, this coin (10 pfennige, rather than a pfennig with a 10) is only worth face value, about 5 cents. It was a common circulation coin until the euro was adopted in 2002.
Since "Deutschland" is German for the country of Germany, the coin in question would be from Germany. "Penny" here is a bit of a misnomer, however, since the equivalent of a penny in German currency would have been a "Pfennig." There were Pfennig coins in circulation from the 9th century until the introduction of the Euro/cent in 2002. It was in 1873 with the introduction of the Gold Mark its division by 100 to equal 100 Pfennige that 1 Pfennig was assigned the value of a penny (or one cent). Previously, the Pfennig had been a coin of more value.

This is an ordinary circulation coin that was used up till the introduction of the euro in 2002. At that time a mark was worth about 50¢ U.S. and there were 100 pfennigs in a mark, so the lowly little 1-pf coin was worth all of a half a cent.
The 10 pfennig coin was first issued by the German Empire on 1873.
