Explanation:

Before 1830s, shivrai was valued at 1/74 to 1/80 of a rupee. There are 150 different types of shivrai extant till date. In 1885, the British government ordered all local revenue collectors (Mamlatdars) to collect all shivrais and deposit them in treasury. The purpose of this was to bring the new pice, worth 1/64 of rupee, in currency by eliminating this native rival.
