Sounds like the slug-rejecter (top portion that gauges if the coins are the right size,etc & aren't slugs) is probably dirty, see if it detatches from the lower half & give a good cleaning in hot soapy water & scrub with an old tooth brush along the coin path, also make sure the bent coin release isn't stuck part way down. hope it helps.
