Stocked items worthless?

i have almost 300 GREEN AND WHITE presents from last year, they were for the higher levels to use so i asume they are worth something. Did nexon change the event again this year? (ty for making me collect 500 pig heads for july 4th then changing it the day before, =_= i also have 200 alter pieces. i dont wanna get scammed and sell for to cheap, so, any idea on its value*?

* (i know it varies from server to server)

You can still use altar pieces.

See, thats why I save all the holiday crap on a separate mule dedicated to hold holiday crap only. It comes in useful the following year.

9 hours later (of AFK, i work at target lol) , i sold all of them, 40m profit. sell your items quick guys!
