making a new character without losing gold?

so i want to start a new char but dont want to lose my gold. or as little as possible

is there anything i can buy and then stash.. then sell on my new char without losing to much in value

Gold is shared amongst all characters so long as they are in the same league.

(Gold won't be shared if one character is Standard and the other is Hardcore for example.)

In other words, you don't have to worry about losing any gold when creating a new character :)
