coins that I need prices for

Just a warning before I start---I'm inexperienced when it comes to grading coins. Here are the coins I have:

1983 small bust canadian nickel I think its an F-12 grade.
1984 Papua New Guinea penny need a site to check the grade
3 United States wheat pennies : 1935, 1944, 1954 need a site for these too


just tell me if you know the price or a site to check the grades of any coin at all

I'm new...

Hey everyone!!!!! I found this site just by looking for some stuff on the internet. All I'm probably going to use this for will be to check prices for my coins. I don't collect so I just sell to friends. I won't do much on here either. Ocasionally I might even post something off-topic. Hope that doesn't bother anyone...
