The 1927 5 cent coin is large and a magnet sticks to it.
There is a coin that is tiny like the 5 cent pieces and it has a large 3 on the reverse. It is dated 1884. It also has a hole above the crown.
I bought these from my mothers estate. Originally the coins were my grandmothers. She was Canadian. We took the coins to a dealer to see what they might be worth and he said "those are Canadian and worth nothing" He did not look at them. He was only interested the USA Coins.
