Price for a spares folder?

[Darth Squirtle]

Thinking about selling off a spare's folder and was wondering what a fair offer would be? I know i could price it out by star city but for some reason cradles and mistys have exploded in price over the last few months, at least compared to when i was buying them 6 to 12 months ago. Haven't listed everything, just the cards that stood out as i was going through it, the others are around the $5 mark.
Hoping to get a playset of beta berserk, revised tropical islands and FBB savannah's out of this folder if i sell it, would that be realistic?

Mistys and Cradles are worth a lot because of how much they're played, they went up for a reason. Most people sell by Starcity prices.

[Twanos]

It really depends on how quickly you want the items to sell vs how much value you want to get from them. Also if you are selling them in bulk or breaking them out individually over time.

If you sell them in bulk your price goes down dramatically because you need someone with that level of money, that is willing to spend it on magic cards, and doesn't already have them. Hence, you will end up selling them for about 30% below low SCG prices is you want it to sell quickly and you might get 10% below low if you're willing to let it take time (months).

If you break them up you will get alot more value on your top end cards but next to nothing on the lower end. On the top end you can expect to get SCG medium to low in a fairly quick sell or over time medium to high. On the lower end cards though IF you find a buyer at all it will most likely be for less than half of low SCG.

As with most things in life there are several variable to consider but I hope this helps.
