What are your barter items?

[Reality Jones]

I've got a nice amount of alcohol (whiskey/brandy), tobacco, tea bags, I think the things people can make most use of quickly will be the instant barter successes but the long term barter items (tools, seeds) will be needed more later on and so rise in value at a later date.

I still don't understand the need to stock up on gold though. A room full of gold is going to be useless post SHTF surely? And how do you work out how much it is worth? I'd rather have a handfull of seeds than a bar of gold that I can't plant or eat!
