My ham experience is just this one which has me a little worried since I didn't pick it and there wasn't a label.
Story behind this ham. Grandma wanted a ham, one of her daughters bought her one for her birthday in October. Delighted grandma realizes she's one person that barely eats meat any more much less a whole ham (and she isn't really fond of house guests family or otherwise). Grandma decides she'd rather have SOME ham and the bone for soup so enlists me to do something with it. So I stop by as instructed to get the ham out of her freezer while I decide hrmm maybe I can smoke it in the UDS and dig through posts here. Well after taking ham out of the freezer, thawing it, then taking foil off I see it's not wrapped so no label and grandma can't remember anything. So I decided to punt, if I mess up grandma's ham I'll get her another. I'm 95% certain it did come from Sam's but that's about it.
Nothing ventured nothing gained right? My biggest real worry through all of this is if it was a country ham they happened to put in the freezer that will be just too salty without giving it a good soak (I thawed it out too close to turkey day for that). However, they look very dark caramel from what I've seen on TV and this looked like a raw ham color after being thawed.
