Hi,
It didn't lose the reeding. the reeding was not there to begin with other than the slight amount that you still see.
When a coin is struck, a collar, as it is called, comes in around the edge of the coin to hold the planchet in place for the strike.
On coins like dimes, quarters and halves and other coins with edge devices like reeding or lettering as in the case of the Proof editions of the
Presidential dollars,
the collar is what "strikes" or imparts the reeding or lettering to the finished coin.
Your coin is slightly broadstruck and by definition the collar does not come into play correctly during the strike.
So where there is no reeding, the collar did not contact the edge of the coin. Where there is slight reeding, the collar made contact.
We can tell that this is not, for example a "
Dryer Coin" because the coin is struck , very slightly, equally off centered on both obverse and reverse.
The collar came in far enough to keep the coin relatively centered but not enough to add the full reeding to the coin.
I hope this helps,
Bill
