First get a reference to that node which depends on how your nodes are added to the Scenetree

Coin Node.gd

extends Node

signal picked_up

func _enter_tree():
    var lvl1_scene = get_node("path/to/lvl1 scene")
    connect("picked_up", lvl1_scene, "_on_coin_pickup", self)

lvl1_scene.gd

func _on_coin_pickup(coin):
    print(coin.name) #do something with coin

The example above does not emit the signal which you’ll probably want to do on some condition met
