Right now there is an interesting discussion going on at the PK forums concerning the new items(platinum/special gloves/boots) coming wednesday.
Due to the decremented mining and chopping times it is expected that prices for basic resources like wood/stone/ironore will drop dramatically (about 75%).
According to this it might be a good idea not to stockpile these items and sell them as soon as possible.
For those of you (constructors) depending on these items, it may be best to postpone purchases until then to get cheaper prices.

Expected prices for platinum: 20 food vs. 3000 gold

Thus resulting in an average value for:

crafting gloves – 92 food vs. 13300 gold
chopping gloves – 212 food vs. 31300 gold
mining gloves – 72 food vs. 10300 gold
magnetic boots – 55 food vs. 7700 gold
gardener boots – 212 food vs. 31300 gold
explorer boots – 112 food vs. 16300 gold

Further there is a lot of ruby stuff coming:
