NICKEL, not "nickle"
BUFFALO, not "buffilow"
Now that we're past basic spelling, 1938 was the last year that buffalo nickels were minted. They were only made at the Denver Mint, and then only until the new Jefferson design was available. However, there had been plans to make them in San Francisco as well but when that didn't happen, the "S" mint dies were recut with a "D" for use in Denver. As a result there are 2 varieties:
Nickels with a clear D mint mark are worth $3 in worn condition, $4 if almost like new, and around $10 if uncirculated.
Nickels where the recut "S" shows underneath the D mint mark are worth $6 to $30 depending on condition.
Buffalo head nickels were never made of silver. See the related question below for the value of a regular 1934 nickel.
A 1934 Buffalo nickel is not a rare coin, retail value for a average circulated coin is $1.00-$5.00
The coin is called an Indian Head nickel or a buffalo nickel, not "buffalo head" - after all, it shows the entire buffalo! Please see the question "What is the value of a 1934 US nickel?" for more information.
It's not silver, it's made of copper-nickel like all other nickels except the WWII ones with a large mint mark above the dome of Monticello. There's more information at the Related Question.
Please don't assume that just because a coin is old, it has to be made of silver. Nickels are called "nickels" because, well, they contain nickel. All except the ones minted during WWII are made of an alloy of nickel and copper, with no silver at all. Please see the Related Question for more information.
These coins are also frequently called Indian Head nickels; both names are about equally common. Please see the question "What is the value of a 1934 US nickel?" for more information.
It's a common year average value is $1.00-$3.00
what is the value of a $5.00 silver certificate with dates 1934 D and 1934 C worth in good shape

Please check your bill again. There were no series letters on 1934 silver certificates, and no silver certificate series letters ever went as high as K. Please see the question "What is the value of a 1934 US 1 dollar silver certificate?" for more information.
9,304,009 1934 British sixpences were struck in 50% silver (only half silver) with 40% copper, 5% nickel and 5% zinc.. They are a relatively common George V coin. In mint state they can be worth around £25-£30. In the lower grades expect them to fetch between £2.50 and £15.00 (September 2010 prices). They weigh 2.8 grammes (silver scrap value is £12-a-Troy Ounce) - so scrap value would be around 50-60p.
