There are lots of reasons to shy away from that offering on eBay. Not only is the price way too high and it does look like the coins are in soft plastic (PVC), the only pic with decent focus if the half and it does not look too great. You can't tell anything about the condition of the other coins and since they have clearly been removed from their original mint packaging you can't tell if the coins all came from a single mint set or were cobbled together. If you are going to pay what the older sets really cost, get original mint packaging or at least buy from a truly reputable dealer. At least back to 1950, sets in OGP still exist at fairy reasonable prices (compared to sets that have been removed from the OGP).
