I can't make out the years but I can help identify them. OF course there is the 50 cent from Singapore. It is the one with the fish on the other side. You have two then from South Africa, one older and the other probably a decimal. The one with the Horse like animal is from uruguay ( which is in South America). In the future check out worldcoingallery.com to help identify the type and value of the coins before the auction and maybe you will be better bids. Best of Luck
