Since I'm always making assumptions I'll try and tackle this cryptic request.
I'm assuming the op is saying they have a lot of coins and know nothing about them. If that is the case and they need advice as to how to start or which coins to photo and show us I will suggest this:
Give us information on the type of coins you have:
Cents, nickels, dimes, quarters, halves, dollars?
Add information on a range of the years you may have.
Do you have any silver coinage? Bullion or coins from the year 1965 and earlier?
Maybe just let know how you acquired the coins, how they are packaged, or who collected them will help us figure out what you have. Perhaps it's a coin jar, albums, plastic
Encased Coins, coin tubes.
Consult websites like the following for a fair market value.

If they seem interested in something, then bring it home, give us the details of the coin, year, mint, what they offered you and provide some photos and the experts here will definitely give you invaluable advice.
Key is, give us more info! Otherwise all we can do is make an ass-u-me!
