Bell’s Blended Scotch Whisky Decanter - 1970s 75cl

I just received this scotch decanter from my 91 yr old g pa. He bought it in the 70’s when traveling in Scotland. I haven’t cracked it yet. Waiting for that special occasion.

This decanter is beautifully designed. I was given this as a present
and would like to know the cost

Please would some one explain to me how this decanter commands the price asked for, I have been collecting these decanters for the past 30 years and have all the listed ones here and more that are not shown, this is a a basic old shape brown bell the most popular made by Wade, prior to Wade producing the bottle they were Made by Royal Doulton, and Spode, now if this had been one of those full, then it would be a different matter, for those of you who understand the rarely and value of these, what would be the rarety value of my miniture decanter midsummer ball 20th of June 1998 , because I'm yet to find another for sale, at the end of the day, it's only worth what some one is daft enough to pay, these few notes are written with the greatest respect and not as a sarcastic critism

I bought a bottle of this at auction. Un-opened for $1. I opened it and drank it. Yum.
Cheers.
