lottery, raffle
籤 centers on drawing lots or raffles, where a random selection determines an outcome.
籤 combines 竹 (bamboo) with 韱, which likely contributes the sound. Bamboo strips were historically used for writing lots or tallies.
Bamboo 竹 strips were used to make lots for a raffle. The complex lower part 韱 looks like a bundle of marked sticks ready to be drawn.
For セン, imagine a cent (one hundredth of a dollar) as the price of a raffle ticket: cent -> セン, and you draw a bamboo lot to see if you win.
