Your going to have to give much more info or provide photos. Your going to have to give much more info or provide photos. Impossible to answer with this little info. It's like asking "whats that 1964 Mustang worth"? Condition? Model? Restored? Original? You see my point?
1965 in circulated, 3-4 dollars, as for the other, you might have a Canadian Commemorative medal. What does it say?
The information you have given for the 'Elizabeth D.G. Regina' coin isn't even enough to determine whether the country of origin is British, Canadian, Australian, New Zealander, Jamaican, Papau New Guinean etc. Photos are generally much more useful here. As for your 1965 'Kennedy Coin' I would assume you're talking about a 40% silver-clad half-dollar, which unless its in mint condition is worth about its bullion value in silver, which you can determine by mulitplying 0.1479 (the amount of silver it contains in troy ounces) by the current price of silver per troy ounce....
I have a DG REG FD 1971 Elizabeth 11 New Pence $2 coin. Not sure what all that means but would like to find out. I know a pic would probebly help, but I'm new to this site and haven't figured out how to download pics yet....sorry. I also have a Victorian B.C Canada coin that says it's worth 1 dollar and expires Sept. 30, 1984. How does a coin expire? Does that mean it is worth something?
Can't help you with the New Pence. The Victoria B.C. dollar is a token that was given away and was accepted as currency up to the expiry date. A lot of cities in Canada would have these types of coins to commemorate a special event eg. centennial year of the particular city etc.. They don't have much more collectible value than $1 or so.
Jessi The 1971 2p coin is worth 2 pence (British), approx 3 cents (US). 1971 was the first year of mintage, and over a billion were produced. To confirm, there'll be the legend "NEW PENCE", and a badge of 3 ostrich feathers with the motto "Ich Dien" (I serve) - the badge of the Prince of Wales. Hope that helps ...
