My dad used to take me swimming every Sunday in Salford, Manchester. One Sunday, we came across two pound coins on the pavement, one sitting half on the other one and half on the ground. I remember bending down to check they were real and was made up when dad said I could have them. The following Sunday, we set off for Broughton baths again. In the exact same place, in our path were two pound coins in the same position, one half placed on the other one. If they'd been dropped, they would have landed apart, it was as though someone had carefully placed them there for us.
