We construct a unique data set from succession and bankruptcy sales in Mauritius to investigate the determinants of slave prices between 1825 and 1827. We find that males, females sold with children, skilled slaves and slaves sold during the peak sugar cane harvest season all fetched higher prices. In comparison, handicapped and non-native slaves were sold at a discount. Moreover, the young child premium increased over the period. This may indicate that slave owners did not anticipate that slavery would be abolished in the near future or thought that they would be compensated in such an event.
