Furry Sunday

Moral dilemma day , i have a vintage suitcase full of furs , very very vintage ones they were given to me over 20 years ago by an old lady in the village , I dont know much about furs except the ones with the little faces still attached . I dont have a problem with them these were old before i was born , but what the hell do you do with them ? how do you tell if a minks a mink ? Is it safe to sell them on ebay or do you end up getting petrol bombed ?
 So once again i shut the suitcase and plop it back under the bed . I could use the money if they were worth anything but its a requires a bit to much thought ...Answers please folks
