Somebody can tell me about some website which I can see world coins prices for free?

Answer 1

Have never seen one. It would take a lot of work to do and keep updated. I haven't seen any you pay for either. I have 4 catalogs on world coins that cover from 1600-2001. Each book is very thick and weigh a lot. Cost for the books is over $200.00 and I have to get new ones often, to keep up with prices.Then for ancient coins I have other books and for some other world coins I have even more books. So you see there is a lot involved. I can help on a few coins and do here in answers, but large quantities are to time consuming. Hope I have answered your question, but not the answer you wanted.
