There is no C$ version, so that would be why
Long answer short? A lot.
Long answer long?
I used a combination of the high-value item list, recent trades or trade offers, and the year-of-release rule of thumb. Several of these items have high or interesting values in trading that you may want to research further or discuss with your trading partner, I've bolded these. For uncommon pet values, C$ values are more or less medians of those quoted on the "How much is this worth in C$" thread.

Halo: It's value seems to be fluctuating a little bit based on the trades
here, although in general it's still worth a September '08 pet. I'd recommend asking your trading partner where they value the halo and consulting the FTT.
Dogtag plushie: Similar plushies have some trade evidence
here as going for more than an 09' R/VR.
Animal eggs: The year-of-release rule holds in general. In my subjective opinion, especially the 2010 ones are a pain to find, and tend to go for more than that.
Nature items: Highlighted because they were released for free as a set, so the uncommon-per-item rule is a little shaky. Their value is in being a large part of a set, not the individual pieces.
In general, I'd value this somewhere around 450-500$. The halo is the bulk of the value; compared to it most of the other items are fluff.
Please get a second opinion, I'm not an expert on high-end C$ trading!@aky-mala I'm glad to hear that!
