The Bahamas first printed this series as "The Bahamas Government" in 1965. Denominations started at $0.50 to to $100. The lower denominations were often kept as souvenirs so there were many kicking around whereas the higher denominations have been much tougher to find. My mother used to vacation in the Bahamas and she brought me back a $1 and 50 Cent note. This series was issued after they changed over from the British Pound system so they are Bahamas first dollars. You can find examples of these, including P-18 ($1), at the Banknote Museum http://www.banknote.ws/COLLECTION/c.../BAH0018.htm
and in 1968 another series entitled: "The Bahamas Monetary Authority," & the $1 (P-27) can be viewed here:

The banknotes you posted (P-35) belong to the 3rd and final "The Central Bank of Bahamas" 1974 series:

Since your banknotes have the Allen signature they come from a smaller run and may command slightly more than the earlier, original "Donaldson" signature. However, I cannot tell you whether they would be worth more as a consecutive run (or not). As a collector of world currency, consecutive serial numbers are completely irrelevant in my books ( that was how they were issued but there might be some who like them).
The Standard Catalogue of World Paper Money (SCWPM) use a Pick system to code various banknotes thus the P# so now you'll know the P# of your notes. They are popular amongst world currency collectors but as I mentioned, there are a lot of these and usually the last series are the most hoarded. Higher denominations are very tough to find & command high premiums.
It would be wise to put & keep them in currency sleeves. Leaving them in an envelope may damage them (light, bleach from the paper, moisture). Nice set!
