If you have a 1914 1000 reischmark bill or coin and you want to know its value, it's best to consult with an expert in numismatics (coin and paper currency collection) or a reputable appraiser who specializes in historical currencies. They will be able to assess the condition and rarity of the item and provide you with an accurate valuation based on current market trends.
It's important to note that the historical value of a currency may be different from its face value. For instance, a 1914 1000 reischmark bill might have a face value equivalent to 1000 reischmarks in 1914, but its value in today's currency could be significantly lower or higher depending on economic changes over the years.
