My character has just over 100,000 gold. I am slowly concluding that there is hardly any point in getting any more because there is nothing to spend it on. I don't want to buy houses--I have Maple Leaf Cottage (a Maigrets mod) and that is enough. Stores don't sell anything much I can use except arrows and an occasional potion. (My character is a good alchemist; at last count she had over 500 potions.) Giving money to beggars one gold at a time seems pointless. Am I missing something? It seems that after you have a modest amount of money in Cyrodiil there is little point in hauling loot back to town unless you want to see if you can become a millionaire.

Thems is the breaks. If there is nothing to spend it on then there is nothing to spend it on.

My long played character has 28,644,024 Septims at the present time. She still hauls loot to sell, and yes, it is all pointless. However, it is part of her daily life because that’s what she wants to do, among other things. She also has 500+ torches, 4,000+ lockpicks, and a lot of other things that are never used. Some people give the gold away, others pay taxes, and some even drop it and put it into a chest. Those options require a mod.

First - Maple Leaf Cottage is my all-time favorite house mod. It's just such a perfect house and a great location and the animals are awesome.

Then... yes. There's generally little point in making money once you've made it to the mid-levels. If you buy a house, or even all the houses, all that does is postpone the point at which you run out of things on which to spend money. Generally my characters reach a point at which they mostly don't bother picking up loot at all, and particularly heavy stuff, since that just means they'll have to go sell it and get some more money they don't need anyway.

Thinking about this right now and I came up with an idea I'm going to try out - buying training. I even know who I'm going to try it with - Claudia the Redguard, my longest-running character. She just finished The Collector and hasn't really had anything to do since - she already did the Thieves Guild and isn't interested in any of the other guilds. I'm going to figure out some sort of obscure minor skill that she probably wouldn't have used otherwise but that she'd be interested in learning about, then go track down a trainer and roleplay some training for her. Maybe mod her game so that she can do more than five training sessions per level....

Still won't use up a whole lot of money, but it's something, and it's something new that might catch her often short attention span.

But anyway... back on topic - you're right. Generally there just isn't much to spend money on once you've accumulated some and covered your basic requirements. My marksman characters have ongoing expenses for arrows and all of my fighting characters have expenses for stuff like lockpicks and repair hammers (until they get the Skeleton Key and master armorer, respectively), and... other than occasional weapons or enchantments or spells, that's about it. They just stop paying attention to money and stop bothering with all but the most impressive loot.

Yes, after a time, one's ability to make gold far outstrips one's needs. I use several RP ploys to keep Buffy's cash under control. Her strength is so low that she won't bother picking up anything but scrolls and soul gems to help keep the shops of her Mages Guildhalls stocked. And I've trained her to actually ignore gold coins. We pretend that her clothes and adventurewear require routine replacement for both style and wear & tear. She also pays the stables extremely well to ensure top quality care for her precious mare. And lastly, she donates a great deal of gold; much of it to her friend, the Countess of Kvatch to help refill the city's coffers after such an expensive rebuild of the city, and quite a bit donated routinely to the chapels.

As far as the mechanics of 'removing gold', we simply use the command console. If not on PC, you can always sell the 'Awesome mace of doom' for the shopkeeper's limit of, say, 1000 gold, then buy it back for its full price of 5000. A few such transactions can quickly trim even the heaviest coin purse.
