I don't think this will be a linear process but more like exponential decay, but the parameters decided by the "Hand" lol
Ok lets define as "Age Band" the timeframe of ages of coins a user/market feels they have some value like a comfort zone
Local markets develop their own "Age Bands" that shift forward or backward as they grow or recess, a single currency of variable "Hardness"
Redeemability
If I offer some redeem of new coins for invalidated coins then I could not recycle lost or unaccounted or stagnant coins,
That would put a floor as you say to the coins value, is that necessary? I like the idea that the only value stored in the coin to be the utility as exchange, more like exchange tokens. So If you don't use it for exchange then it has no value

Would not people?l trade them as soon as coins get out of their stated "Age Band"
Besides maybe there is a market even for near expiration coins: let the children play

Variability of the Valid Block Window.
It occured to me that markets will define their own Subwindow in the form of "Age Band" and possibly making the size of the Block Window irrelevant, as long as of course the block Window is sufficiently large to encompass the various markets needs/Age-Bands.
So markets expand/shrink - inflate/deflate their bands at their will.
On the lighter side:
how do you like naming my coin ouro from http://en.wikipedia.org/wiki/Ouroboros multiple puns intended
I even have found a symbol for ouro :Ȣ or ȣ http://en.wikipedia.org/wiki/Ou_(ligature)
