(one's) two penn'orth

One's ideas, opinions, or point of view. ("Penn'orth" is a contraction of "pennies' worth.") Primarily heard in UK. If anyone wants to hear Dr Sanders' two penn'orth about the anti-vaccination debate, you can tune in to his podcast this Friday. I'd just like to put in my two penn'orth before we finish up the meeting, if I may.
