full_context: Document 1: Cape Verdean escudo: After independence on 5 July 1975, notes were issued for 100, 500, and 1000 escudos on 1 July 1977. The next series of notes was introduced in 1989 and consisted of 100, 200, 500, 1000 and 2500 escudos.
Document 2: Zimbabwean dollar: The first Zimbabwean dollar was introduced in 1980 and replaced the Rhodesian dollar at par. The initial ISO 4217 code was ZWD.

As a result, in both the official and parallel markets, the currency's value eroded rapidly over the years, and by July 2006, the parallel market value of the Zimbabwean dollar fell to Z $1,000,000 = GB £1.

Document 7: Coins of the Indian rupee: The move towards decimalization was afoot for over a century.

It, however, was now divided into 100 'paisa' instead of 16 annas or 64 pice. Effective from 30 June 2011, all coins in denominations of 25 paisa and below were officially demonetized.
