I need help grading

I recently got these 4 coins from my grandparents, I am a collector but I am not very good at determining a grade and value. Different websites say different things. What is a accurate website for coin pricing? What are some tips for grading? And what is the value of each of these coins?🤷‍♂️

Without pictures, it will be very difficult for anyone to help you. Could you please post clear pictures of each side of your item?

Hi, based on what I can see, these coins would be VF (Very Fine). There's medium to light wear while the major details are still visible. I recommend checking out the NGC World Coin Price Guide for a value estimate, as well as Numista's coin catalog.

Using Numista's Coin Catalog for price estimates:

1. 1964 50 Cents - Elizabeth II (Canada) ~ $7 USD
2. (3) 1966 1 Dollar - Elizabeth II (Canada) ~ 12 USD/Coin

Lastly, for some tips for grading, check out the Royal Canadian Mint's article on the Sheldon Coin Grading Scale. I hope you find this helpful!
