Coins Worth Grading?

no . new members need to learn a lot more about coins, before they ever consider spending money on grading..

not worth the money nor the time and effort unless they are extremely special as mementos only. On the plus side your photos are really good for a new person dropping by. Feel free to join in, one coin per thread in the correct grading forums for advice, We can definitely advise grades on coins with nice in focus photos.

It is easy to check the current (approximate) retail value of world coins from the NGC "world coin price guide". They also have prices for US coins. The values tend to be high but it gives you an idea. Your Mercury dime is damaged-it is only worth the silver value. the third one has chop marks. Still collectible assuming it is not fake, but no point sending to to be slabbed. the third and 4th coins are often faked. At a minimum, you need to check the weight and see if they are magnetic. The yellowish stain on the last item gives me cause for concern.
