At some point many kids are offered the exciting chance of rolling all of the coins in their parent's jar of everfilling loose pocket change back before those self sorting coinstar machines started being a common thing & that gives most people an idea of just how time consuming it can be to organize even a small pile of awkward to carry coins dumped on the floor for them but that awkward pile isn't a thing in d&d because 50coins =1 pound sorted or not & 1 pound is insignificant given PC carrying capacities. I was watching a video
At about the 18 min mark where the video is pegged Shad mentions a chest of gold & talks a bit on the logistics about lots of coins D&D has 5 different 10x /q 10th stepping coin denominations plus trade goods & things like easily portable gems/artwork but with carrying capacities 50coins=1 pound ensures that the party won't really need to think much even if the gm gives them a huge pile of copper & silver. If you've ever handled money in retail or similar you probably know just how heavy & awkward that a 10 3/8" x 5" x 3 1/4" 500$ box of quarters filor similar can be at around 25 pounds when filled with 50 painstakingly rolled up rolls of quarters . Using the standard 50 coins =1 pound it would be 40 pounds for that box of 2000 quarters, but2000gp is nothing really & even if the party found a significant sum like 50,000gp that only works out to around 250 pounds across a party of 4 & tha's not a significant amount of weight even if the party is already carrying their gear & such. Sure the GM can use a larger pile of copper or silver, but that tends to just invoke " that's only like a couple thousand gold... does anyone care that much or should we just leave it?" unless it just leaps into completely credibility straining mountain sized piles of coins where the players couldn't really do anything on their own with it beyond sell a map to it or something.
If some number of unsorted unstacked or unrolled coins amounts to one bulky item though it would solve a lot of trouble. Adding a simple difficult choice like deciding if this gold vrs ditching rations(not to mention that ###gp mug) or spending a huge amount of time sorting it into stacks/rolls/etc can change how players value those not so valuable trade goods gems/art/etc. Alternately it could introduce real value in having henchmen & a donkey or something to carry & sort this kinda stuff
With the followers/henchmen/= type things it becomes even more important to have some kind of xxx unstacked coins=1 bulky item. If even 1-2 players have a follower or two that dramatically ups the size of a pile that is trivial to manage. Sure a GM could say "no your followers refuse to carry coins becausre they are cooks & pack animal handlers" or something but at a certain point the players can just offer too large a percentage of the pile they would otherwise leave behind for that to seem credible. I may never have had a job unloading armored trucks, but if my boss rolled up with a moving van of quarters & offers me half of everything I can carry to the bank I could probably carry a whole heck of a lot quite happily not caring that's not my job & probably not that unusual in that regard.
