How old is my white horse blended scotch whisky?

[jeeperfreak]

I know that I am new on here but I do not know anywhere else to go to find out how old this whisky is and what it may be worth. I don't want to drink it if it is worth something Thank you in advance for any help! This site is not letting me post pics yet so here is a physical description.

The bottle says it is a 1/2 gallon and has 4 letters ADHG and then No. 81864 on it. it is a yellow label with black lettering and on the right side of the "white horse picture" there is red letters saying "White Horse" but the word "Cellar" is not on the bottle after the red words "White Horse". There is a metal tin type lid on it with a twist tie and a red tax stamp/label across the lid of the bottle. There is a white horse poorer thingy that is with it but feels like an old plastic with black letters on it that say White Horse Scotch. The back has a label similar to the front being that it is yellow with black lettering and the red words "Whtie Horse" but it has a picture of an old WhiteHorse distillery on it.


Any ideas anyone?
