If by evaluated you mean finding their value, this website shows past sales and members buying cost. The Standard Catalog of World Coins will give you some values or https://www.ngccoin.com have coin values from the SCWC and or numismaster in USdollars.
If you mean evaluated for authenticity you could post images of coins on this forum to see what members think, but please just one coin per post, or alternatively you could take the collection to a coin dealer or auction house specialising in numismatics. My advice would be at least to add them to your collection first to learn about them, finding some information about rarity and possible value first before taking them to dealers.
As for the question, what to do with them, you can keep them for your children, grandchildren, learn history from them or just learn about numismatics from them. Alternatively you could put them up for sale on eBay or gift them to someone who is interested in collecting coins if you don’t want them, that is entirely up to you.
If you PM me I will send you my postal address, I love weird and wonderful coins 😉
