Need to have really old coins appraised.?

I’m searching for someone who could give me an idea of the worth of some coins. An 88 year old friend of mine asked me to investigate the value of some coins that are dated from the early 1800′s to the early 1900′s. Most are in good condition, all of them having been circulated, and some (a two cent American coin) I have never seen nor heard of before (I’m considerably younger than she is). I’ll list some of the coins below, of which she has several, and would appreciate it if someone could contact me in regards to same, as I don’t know any other source to check with at this time. Thanks.

AMERICAN
1) 1842 Dime
2) Two Cent Coin (one side is worn and can’t make out the date)
3) 1899 Dime

CANADIAN
1) 1917 "One Penny" (very large. A woman warrior on one side holding a shield and trident, and the other side shows the head of a man and says "Briton", among other things. I THINK it’s Canadian.)
2) 1899 "Once Cent", "VICTORIA DEI GRATIA REGINA"
