"Einen thaler" means roughly "in a thaler" and appears on fractional currency of German states in the 18th and 19th centuries. There will be a number before the words; thus "120 einem thaler" means that the coin's value is 1/120th of a thaler. The value of the coin would depend on the specific denomination, the issuing state (there were perhaps 100 different German states, or combinations of states, and Free Cities which issued coins), the year of issue, and the condition of the coin. Note that determining the issuer may be a challenge - the copper coins of the German states often had only a shield, crest or royal insignia to indicate the issuer, rather than the issuer's name.
"The German name Thaler comes from the Bohemian coin minted in the 16th century from silver mined at Joachimsthal in Bohemia. Not long after issuance, these coins gained the name Joachimsthalers. Subsequently, the coins were called "thaler" regardless of the issuing authority[1], and continued to be minted until 1872." -- Wikipedia.

We cannot see you rare coins. Since we cannot even see your rare coins, we do not even know if your coins are indeed 'rare', what they are, their condition, when they were made - we do not know anything. Please specify in a different question what your coin is, the date it was made, and the condition it is in.
