Help me catch up please... Ivory Hammers, etc

Last night I had one of these drop, a gold req 9, and got some rather hearty congrats from the mission party...

... are these considered rare skins? Also, if you all would be so kind, what other Nightfall skins are out there considered in the rare category?

Thanks for letting me tap into your wisdom all...

i find ivory hammers pretty often. they are probably arent worth much like other hammers. if youve ever seen a bladed recurve bow drop, those are really nice and ive never seen a gold one. also i know elemental blades are very rare.

You got congrats because you get a req9 Gold.

a req9 gold will get you congrats nomatter the skin, because golds even dropping is "rare".

Bladed axes are also rare skins.

If you are new to the game every item will be rare to you. After you get around the game and get a feeling of the common drops and colors then you will get a sense of what rare is.

You will most likely get a congrat with gold or purple as long as is a good drop. I go with the flow if I dont see it often is rare to me and if you get that feeling just dont sell it without doing your research you want your monies worth.

I always say "grats" if a gold drops, no matter what skin/req it is.
