This item can be crafted at the Alchemist with crafting materials.
Which, going by item value in Gold, totals 4,715 (plus 20 Gaia’s Tears, which don’t have a direct Gold price).
If we look at how much Gaia’s Tears cost compared to Gold:
We see that Gold is worth (at the time of writing) almost twice as much as Gaia’s Tears. Prices for tokens in $USD will always fluctuate based on what’s happening on the market, with the prices going up when ingame demand increases and going back down when demand decreases. Free economy, etc. But, for the sake of argument, let’s assume it won’t deviate too far outside of [Gold/4]<Gaia’s Tear>[Gold*4], which would give it a fluid value of 0.25-4 Gold. At most this would put the value of 20 Gaia’s Tears at 80 Gold.
Bringing the total Gold for a Magic Resistance Potion to 4,795
