This was interesting to see when some minted coins showed up last night, after running the client for a few weeks (off n on)!

Looking up my address: 9jzrgBnBY8V7LH9cSgvyYMtL9wbrgyt6RV on philosopherstones.org/block/
the transaction:
f6e41098360c26faf62203462bcb93be935e453becb674b96095b48991aa3023
The
Operation History Tab show my POS reward as 43.99589000 PHS
but,
when I go to the
Unspent Inputs Tab, the POS amount shows as 98.88279800 PHS
a difference of 54.886908 PHS.
My wallet only shows the 43.99589 amount as well. After looking thru all my POS rewards, the same thing has happened with all of them!
******Another reward just came in

as I typed this and it also has different amounts between the two "info" tabs on the Block Explorer.
Can anyone give me some insight on what's going on?
Two clues to this, one: following the transactions connected to each reward, it seems some of the newly minted coins are being "sent forward" to future POS rewards?
the second clue, under
Transaction Details, it shows some of the coins "Not Yet Redeemed".
Love to find out where to "redeem" a bit over 100 PHS that hasn't been credited!!

In operation history you see your reward. The amount of new coins credited to your account. In unspent inputs you see all your coins, that you can spend. The amount of coins that was before reward plus reward it has minted.
