Hey,
First of all welcome to Habboxforum. I'm not sure when we are merging but it's going to be very soon we've not had any official announcement yet i do believe so i'm not sure when. For UK values make sure you use
www.Habbox.com it's the best and the only one really, updated regularly etc etc.
So for the values, firstly it's hard to give any figure to the amount something will be worth after the merge until we actually merge and trades start to occur but i can give you the values of each item on each of the hotels, and this should give you a rough idea as to whether something will be increasing or decreasing in value.
Melbourne Cup/Gold Cup
AU: 10HC
SG: 197.8HC
USA: 650HC
UK: 70HC
Could increase looking at the values. They are used loads in casino's on UK and i'm sure that the same on USA, and as trends show casino rares are more desirable and thus are worth more.
Flying V Guitar
AU: 0.25HC
SG: N/A (Can't seem to find it on SG, maybe it's unreleased)
USA: Same as above
UK: 1008HC
Although it is unreleased (i think) on two for the four hotels, and is worth a high values on UK, i can't see this doing amazing, don't get me wrong i think it'll increase but with a value as low as 0.25HC on AU there must be loads of them and thus i won't be worth incredible values.
1800 Reverse Teleport
AU: 1.5HC
SG: N/A
USA: N/A
UK: N/A
To my knowledge this is a promotional item released on AU only. Much like UK has idea agency teleports on UK. The good thing is that it's only on AU, the bad things are that there seems to be quite a few of them and due to them being branded they are only really personal to AU and not the rest of the hotels, they won't want them because they don't understand where they come from. Can't seem them rising much, if at all.
AU: 1HC
SG: N/a
USA: N/a
UK: 10HC
Unreleased on 2 for the hotels and it is kinda uncommon on the UK hotel. I think this could rise. Plus the green parasol is only on our hotel, i could see people trying to buy these to get a full set, so maybe if they are buying green to get a full set they will also start buying orange too, which means an increase.
Hope that solves all your queries. If you have anymore please do feel free to ask :D
Make sure you tell all your friends on Habbo AU about Habbox.com for rare values and HabboxForum.com so they can come and say hi to us.
Thanks
