If anyone knows please and thanks.

the range should be 1.5-1.8m

Well, since it's only 100 credits and you can buy a 100 credit gift card from user shops for 2m and buy a goody bag from the cash shop yourself, I would say it is worth 2m maximum. People won't pay more than that unless they don't understand how things work.

Thanks.

Locking, as this item is priced in the shop search. :)
