First welcome to the forum. As for your nickles unless they are high grade uncirculated they have no extra value than being able to spend them for a nickle. If the 47 has a dot after the 7. it has a bit of collector value. They made three types that year, plain, with maple leaf after the 7, and the one with the dot.
The 1947 nickel is an interesting one. India gained independence in the early part of 1948 and left the mint scrambling for new obverse coinage tools. Why?? you asked, what does it have to do with Canada? Well the obverse was up till then since the beginning of King George VI's reign in 1937 inscripted with "GEORGIVS VI D:G:REX ET IND: IMP:, short for George VI by grace of God king and emperor of India. The same phrase has been in used since George V in 1911. With India's independence in the beginning of 1948, no way could the mint keep on using the phase "IND: IMP:" The tools would not arrive for several months but there was still great demand for all coin denominations. Hence coins were struck in 1948 using the 1947 obverse. But to distinguish these coins from the 1947 coins minted the previous year, the mint used a maple leave privy mark at the end of the date to show this distinction. To further interest the matter though, some of which have only a dot. So there you have it, there would be 3 varieties of the 1947 nickel as bulldawg had said. Here's the market value for the coins dated 1947. -----------1947 plain--------1947 maple leaf--------1947 dot mintage---7,603,724--------------9,595,124----included in 9,595,124 VF-20------------------------------------1$--------------40$ EF-40------------2$----------------------2$--------------90$ AU-50------------5$----------------------5$-------------200$ MS-60-----------12$---------------------12$------------275$ MS-63-----------30$---------------------25$------------450$ MS-65----------200$--------------------175$-----------2000$ Better get that magnifying glass!
