* Spot gold down about 4.5% this week, the most since early June
* Silver, platinum and palladium also head for weekly declines
Nov 13 (Reuters) - Gold firmed on Friday as a largely in-line US inflation reading alleviated some bets on a bigger rate hike, but Thursday’s selloff to a more-than-a-year low kept bullion on track for a weekly decline.
Spot gold ticked up 0.1% at $3,879.71 per ounce as of 2:05 p.m. ET (1905 GMT), after briefly touching a session high of $3,922.97 when the US Producer Price Index data came out.
US gold futures for December delivery settled largely unchanged at $3,886.30 per ounce.
