The coin assemblages are all equivalents in terms of their monetary value. They each equal a total of £1. Where each sculpture differs is in the type of coin used, the quantity of coins used and the final size and time taken to make each one. Their final value differs as the amount of work I have put in to each one changes with the quantity of coins used to make up the monetary value of £1. The one pence assemblage, took a lo longer than any of the others. Whilst it uses the lowest value coin, it' the highest in value when the time taken to make it is taken into account.
