I'll use the $ until it wont buy anything anymore. That day aint far off, in my opinion. I also have gold coins, but not all that many, cause I'd rather be making 40% per year (after tax and ss) with the money. That can be done, year in and year out, by investing 100k at a time, in a used 18 wheeler with a "reefer" trailer, by the way. Now, in the last 6 years, gold has gone up from $450 an oz to over $1300 an oz, so if you weren't making the sort of money I make on your investments, you lost out, big time. The trick is in getting a team of drivers who will be dedicated to the job, for 50k a year less than typical drivers. That can be done. The rig goes for 60k or so, with 1/5 million miles on it. You'll be putting 1/4 million miles a year on it, so it will need repairs every year or so.
