OSR Treasure Placement

For protected treasure, I always use its protector’s treasure type, even in dungeons (RAW, you're supposed to reserve that for wilderness lairs). I also always use the average value listed for treasure types, in gold pieces, though I generate magic items as normal. I'm not sure if listing average values is just an Old-School Essentials thing, but that's my go-to dungeon crawler!

For unprotected treasure, I always use the average value for unprotected treasure types. This isn't calculated in most OSR products, so I created the table below. I still generate magic items as normal. 

I calculated average gem and jewelry yield using spreadsheets from Delta’s D&D Hotspot. The average expected value for gems is 194.5 gold pieces, and for jewelry 1,050 gold pieces. The average yield of gems or jewelry is determined by multiplying their average expected value, their percent chance of appearing, and the average quantity that would appear. Additionally, these averages were calculated assuming gold pieces always appear.
