Records of former Indian currency oddly lost (6)
I believe the answer is:
annals
'records' is the definition.
(I've seen this before)
'former indian currency oddly lost' is the wordplay.
'former indian currency' becomes 'anna' (I can't explain this - if you can you should give a lot more credence to this answer).
'oddly' means one should take alternating letters.
The alternate letters of 'lost' are 'ls'.
'anna'+'ls'='ANNALS'
'of' is the link.
Can you help me to learn more?
(Other definitions for annals that I've seen before include "Chronological records, yearbooks" , "History of events year by year" , "Yearly records" , "The Four Masters wrote them in 17th century" , "Registers" .)
