I want to know the answer to the following question:
What is the approximate modern value of two guineas in 1830?
All the background I'm provided with is that "Under the 1830 Act any householder who paid rates could apply, with a one-off payment of two guineas (roughly equal in value to £168 today), to sell beer or cider in his home (usually the front parlour) and even to brew his own on his premises.". Is that enough to answer the question?
