What is the value of a bottle 1968 blended scotch whiskey 1.75 liters?

I cannot give you an accurate value for a bottle of 1968 blended Scotch whisky. Here's why:

* No brand or distillery: You haven't provided the brand or distillery of the whisky. The value varies wildly depending on the producer.

* Condition: The condition of the bottle is crucial. Is it unopened, in its original box, with labels intact? Any damage, wear, or missing elements can significantly affect its value.

* Rarity and Demand: Some 1968 blends might be very rare and in high demand, while others are more common.

* Market Fluctuations: The value of vintage whisky is constantly changing based on market trends, collector interest, and other factors.

To find the value, you need to:

1. Identify the brand and distillery. Look for a label or any markings on the bottle.

2. Assess the condition. Examine the bottle for any damage, wear, or missing components.

3. Consult experts: Seek advice from professional whisky appraisers, auction houses, or online resources dedicated to vintage spirits.

Remember, online estimates can be unreliable, and it's best to consult a professional for a proper valuation.
