Personally, I'd go with none, because really the points are a game-side consideration rather than a narrative-side one. An Elf that is 300 years old doesn't get any more points than the fresh faced just-gained-majority new kid on the block.
However, if you really want to give free points, I'd just work it. Judge what the average number of sessions it takes your party to completed an Adventure Phase. Multiply that by average session length in hours, and that's how many points they'd get per adventure. Then decide how many adventures they'd be doing per year in this quiet period, multiply that by number of points per adventure, then multiply by 15.
It's worth noting that there is generally a ten year limit for characters, and narratively that makes sense. Old or even middle-aged adventures don't move like they used to...and don't last that long. If you have any Men in the company, that might be a narrative issue, because they'll have been going for 25 years or more...which doesn't quite fit. It's up to you though.
