Short answer: for reports, and for default conversion rates for fresh 
transactions. You need to keep the ones you'll need in future; if you 
don't run reports, then you probably don't need old conversion rates.

Another example:

I open my Assets:Foreign Currency:Euro register and enter a debit dated 
2009-07-20, EUR500, carefully choosing a new "Description" so it won't 
inherit data from any existing txn. After choosing a suitable "Transfer" 
account, keying "500" in the Debit column and hitting Enter, Gnucash pops 
upan exchange-rate window with a rate handily filled in: 0.8890625, or 
EUR1=GBP889062, in this case. Where did it get that from? In the Price 
Editor, I see an entry corresponding to a purchase I really made, on 2009-
07-19, the rate showing as 0.889063. Gnucash has looked up the nearest 
(or perhaps the last preceding) Price Database entry to the txn date I've 
just entered.

The Price Database also provides the rates used when converting 
commodities / currencies for Reports, but I don't make much use of the 
ones for which that's relevant so you'd need to ask someone else.
