It's not in great shape, but is it valuble? I also have 1937 uk three pence and a 1966 six pence,..... any value worth getting excited about?
The indian head is not Canadian. Canadian coins do not have Indian Heads. If you can post a pic or give a better description maybe We can help identify it. As for the other two they are probably not worth much since they are small denomination of a very common currency.
An 1878 Indianhead would probably sell in the $5-10 range in Good. If you can read the "LIBERTY" on the headdress as a general rule it is in at least Fine condition and you could easily get $20-25 on a site like ebay. Of course it may be in even better shape and worth more - but most aren't. I have sold alot of Indianheads on there. They are easily moved as they are a very popular coin.
