How hard could it be to double 1p?

Not hard at all it seems. I was sitting at the table in the front room when I noticed a rather unattractive penny sitting on the table under some toys.

A quick enquiry revealed that no one was claiming ownership and so the penny became mine.

I am now at 2p and must find a way to trade this up to 4p.

For the doubters: You will see that as this goes on I will only need the steps I've indicated.
