Well, I have some of each!
If OTOH your question means "How do you tell the difference between a Type 1 and Type 2", you can take a look at the images.
A: Nickel (II) Iodide = NiI2 1 Nickel 2+ and 2 Iodide 1- Pronounced " Nickel two iodide"
The kinetic energy of a falling nickel can be calculated using the formula KE = 1/2 * m * v^2, where m represents the mass of the nickel and v is its velocity. By knowing these values, you can plug them into the equation to determine the kinetic energy.
In one molecule of nickel hydroxide, there are two oxygen atoms. This is because the chemical formula for nickel hydroxide is Ni(OH)2, meaning there are two hydroxide groups, each containing one oxygen atom.
1. Nickel was discovered in Sweden 2. Nickel was discovered by Alex Cronstedt 3. It was discovered in 1751 4. The U.S. nickel contains 25% of nickel 5. Very useful, but toxic to humans 6. NICKEL got its name by the german word kupfernickel 7. Kupfernickel means DEVIL'S COPPER 8.Nickel is commonly found in meteorites
NiS is the formula for nickel sulfide. The nickel(II) ion has a 2+ charge and the sulfide ion is 2-. When the Ni(II)2+ bonds with the S2- the 2s cancel out and you are left with NiS (nickel sulfide). E. Morris
A Type 1 Buffalo Nickel has the words "FIVE CENTS" raised on a mound at the bottom of the reverse side, while a Type 2 Buffalo Nickel has the words "FIVE CENTS" recessed below the mound. This change was made to address issues with the coins wearing down quickly in circulation.
By "type" I assume you mean "mint mark" because there are no known design varieties for 1926 nickels. The mint mark position on all buffalo nickels is on the back under the words FIVE CENTS. No mint mark = Philadelphia, S = San Francisco, D = Denver. Philadelphia issues are common; as of 01/2009 retail values range from $1 if worn to about $10 if almost like new. 1926 Denver nickels are harder to find - their range is $8 to $150; San Francisco nickels are the scarcest for that year with a range of $17 to almost $1000.

About $1 in average condition, $2 or 3 if it's only slightly worn.
A circulated 1942 buffalo nickel typically holds a value of around $1-2, depending on its condition and mint mark. It is always recommended to consult with a professional coin dealer or appraiser for an accurate valuation.
All buffalo nickels were struck in the same alloy of 75% copper / 25% nickel that has been used for all 5-cent pieces except the famous "war nickels" made during WW 2.
With a small "S" under the words FIVE CENTS, about $1-2 in average condition. With a "D" or no letter, the upper range for an average circulated 1929 nickel* is about $3.
The 1913-D Buffalo nickel has two distinct varieties, the first type shows the buffalo on a mound, and the second type has it on flat ground and values are very different. Assuming the coin is circulated, the type 1 has retail values that run from $14.00-$60.00. The type 2 has values of $90.00-$258.00. The coin needs to be seen and graded for an accurate assessment. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched or have been cleaned have far less value if any to a collector or dealer
All buffalo nickels were struck in the same alloy of 75% copper / 25% nickel that has been used for all 5-cent pieces except the famous "war nickels" made during WW 2. The latter were made of silver, copper, and manganese because nickel was a strategic war metal. The term "nickel" was applied to the coin long before the buffalo design was adopted.
For the type I the mintmark is filled and the type II the mintmark is clear.
Because the 1913-S Buffalo nickel has 2 distinct varieties, the values are very different. Take the coin to a collector or dealer because values in the low grade of G-4 for the type I is $40.00 but the value is $300.00 for the type II.
