If you are wanting to give items, I would recommend doing Consumable and Expendable Extraordinary items. I’d recommend checking out @SamWilby article:

You can still “give coins”, just describing amounts of Gold and silver.
Here’s a breakdown of rough gold/dollar amounts you could use to give an idea of how much they find for each WL. Note these are broken down by the decimal WL system I use, but you can just look at it as a range of values within the WL. These are just abstraction of roughly what could be around that WL. WL is more than just straight money/currency after all.
WL 0.1 - 2 Silver / 20 Copper
WL 0.3 - 6 Silver / 60 Copper
WL 0.5 - 1 Gold / 10 Silver / 100 Copper
WL 0.7 - 1 Gold & 4 Silver / 14 Silver / 140 Copper
WL 0.9 - 1 Gold & 8 Silver / 18 Silver / 180 Copper
WL 1.1 - 2 Gold
WL 1.3 - 6 Gold
WL 1.5 - 10 Gold
WL 1.7 - 14 Gold
WL 1.9 - 18 Gold
WL 2.1 - 20 Gold
WL 2.3 - 60 Gold
WL 2.5 - 100 Gold
WL 2.7 - 140 Gold
WL 2.9 - 180 Gold
WL 3.1 - 200 Gold
WL 3.3 - 600 Gold
WL 3.5 - 1000 Gold
WL 3.7 - 1400 Gold
WL 3.9 - 1800 Gold
WL 4.1 - 2,000 Gold
WL 4.3 - 6,000 Gold
WL 4.5 - 10,000 Gold
