I'm not too good at lower-value items but I'll do my best. I wish items had markings of what year they were made somewhere on them. Thought I wasn't going to look up every single item in the second trade and then I did lol.
Item Trade 1:
Pet Value = 2011 Rare + 2020 rare + 2021 rare + 17 C$
Item Value:
This Cat Plush is a
2014 christmas item. Usually items go for an uncommon of their year so if we assume the 2:1 rule going up in years, the cat plush alone is worth 2 2015 uncommons/1 2015 rare. This is the kind of calculation I'll be doing for the items.
So first I'm going to try to find items = to the value of the 2022 store pet (2011 rare)
Squid Inner Tube + Red Arm Floats + Blue Scuba Flippers from Summer 2012 = 3 2012 uncommon
Pizza 2013 item = 2012 common
PJ Bottoms 2013 summer item = 2012 common
3 2012 uncommon + 2 2012 common = 4 2012 uncommon = 2 2012 rare = 1 2011 rare. That's the store pet.
Next I'll find the value of the C$, though it really depends on how you value it.
If you go by
This list then 17 C$ is equal to a 2013 rare. But also could be equal to a 2015 and 2022 rare or any combination of rares that add up to that amount.
Plushies can be worth 2 uncommons of their year but for this trade I'll just calc them as one.
Cat Plush 2014 Christmas = 2015 Rare
Sufganiyah 2015 Hanukah = 2016 rare/.5 2015 rare
Animal Egg 49, 52, 53 2015 Easter = 3 2016 rare/1.5 2015 rare
= 3 2015 rare. I'd say this is worth more than 17 C$, personally.
Next for the value of the regular 2020 and 2021 rares
Striped Armchair 2014 Christmas = 2015 rare = 2 2016 rare / etc
Worth more than both the 2020 and 2021 rares in the trade and now the items are overpaying, whether or not you value plush at 1r of their year.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxTrade 2
Pet Value: 3 2014 uncommon + 2020 uncommon
Item Value:
Plushies and animal-items tend to be high-demand and go for more than other items. As such I'll be valuing them at 1 rare per their year. If the item isnt a plushie I'll add 1 year to it to make it a rare. (I.E. 2020 Not-plush item = 2021 rare)
Zombie Dog Plushie x 3 = 3 2020 rare
Sharkie and Stripey = 2 2019 rare
CS Plushie 8, 20 = 2 2020 rare
Acid Bat, Skeleton = 2 2019 rare
Heart Twinkle Lights = 2021 rare
Wonky Plush x4 = 4 2020 rare
Bouncy Bat x4 = 4 2020 rare
Squid White = 2020 rare
3 CS Dog Plushies + 5 Reindeer Plushie = 8 2020 rare
Rats = 3 2020 rare
Raccoon and Opossum = 2 2020 rare
Total: 27 2020 rare + 4 2019 rare + 1 2021 rare
1/2 = 0.5 2020 rare
27.5/2 = 13.75 2019 r + 4 2019 rare = 17.75 2019 rare
17.75/2 = 8.875 2018r
8.875/2 = 4.4375 2017r
4.4375/2 = 2.21875 2016r
2.21875/2 = 1.109375 2015r
1.109375 = 2.21875 2014 uncommon
Technically slightly unfair to pet side by ~0.8 of a 2014 uncommon and 1 2020 uncommon if you value plushies at a rare of their year. If you don't then it'd still be unfair to the pet side and instead be worth 1 2014 uncommon.
After doing all of that I realised I forgot to add the Dante Bat Plushie which is = to a 2020 rare which adds 0.03 of a 2015 rare. Not much of a difference and still leaves the items underpaying.
Personally though, I'd take this trade if you like the plushies. It's bulk plushies for a few pets and none are rare, + deer tend to not have great demand.
