hi, i have had this train set in my closet for many, many years. the label says "old timers". they are all still in their original boxes with the original price tags. the boxes have never been opened. there are packages with the tracks also and a bender. i was wondering, are they actually worth anything now to anyone? i know they are at least 43 years old. how would i find out what there worth and if anyone would like to buy them. your response would be appreciated. thanks.
