I don't have gold as an investment, I have it to store wealth as I have more faith in it than in fiat
I mostly buy sovereigns as I have a personal preference for them, but I am happy to buy larger coins, I like the 1oz Royal Arms for example. I store wealth in gold and sell it when I need fiat, for example a large portion of my stack was sold in the last three months of 2023 as I decided I need to pay down my mortgage. I sold all sorts of different gold, from 1/4 sovereigns and 1/10oz Brits up to 1oz coins, though 80% was sovereigns. I did not really struggle to sell anything even in a depressed market, though a few bits needed to be put up a couple of times or the price dropped. I never take into account what I paid for a coin when I sell as it is counter-intuitive, I only ever look at what fiat I need to raise and what I need to sell based on current prices to achieve it, I then sell either what is popular at that time or what I can most easily be parted from. I will also sell sometimes when I do not need to, this is to make sure I maintain my reputation and feedback as a seller on this and other platforms, and to give me more capital to go coin hunting. I also take this into account when I buy, so I do not only concentrate on what I love (Victoria Young Head sovereigns in case you were wondering) but I also try and buy a variety of different things and what I think will sell well should I need fiat in a hurry. Makes for an eclectic stack that's for sure.
Because of my recent sales my current stash is barely worth paying for a lock box, but now my mortgage payments are reduced it also means I can spend more per month replenishing it, happy days
