Need help price-checking some items!

[PoingoBoingo202]

Recently I had someone show interest in some items that I own from the April 2013 Earth Day Set!
Though sadly I don't want to ask an improper price from the person interested- I've looked on the wiki and SO many other places to try and find out what price this set was when It came out so I can try and properly price the items- but I can't find anything!
If someone could lend a quick hand, I'd be very grateful!

These are the items from the set that I own:






This is only 13/36 of the items from the pack.

you might get more responses asking in these threads: item values/c$ values

afaik this set was free to claim, so was not priced when it came out! however, it does have pretty good demand; usually items are worth an uncommon from their release year (for 2013, 1-2c$ per item), but i have also seen (here) that this set might go for more like an euc/rare per item just because of the age & demand, which would be anywhere from 6-24c$ (an 2013 euc is 6-8c$ and a rare is 18-24c$)
probably the larger items like the shrubs, fountains etc. would be on the higher end, and the smaller flowers and mist type items would be less.
i hope this helps!
