There are street musicians here everywhere.  They call it busking.  If I like their music I give them some money.  We also give homeless people a coin.  The UK coins are in pounds, like the U.S. quarter, dime, nickel and penny.  There are a lot of types of UK coins.

Here is a one pound coin below.  If you have one dollar and 30 cents in U.S. money, you can trade it for a one pound coin.  If you only have one dollar, then you’ll only get 77 pence.

We gave the harp player a two pound coin because he let my brother and I play his harp! In order to busk in the tube tunnels, you need to be really good and audition for a permit.  See my post where I busk with my violin here.
