I would agree. I took some gold Krugs on a cue purchase about 2 years ago.. they were 1800 each, we received 10. I still have them. Could I have turned 18K into 26K+ in the same timespan. Maybe, but it was not a concern then and not now. They are market regulated and much safer than relying on internet hype and coins are never going to be the "next" Balabushka and you aren't waiting for that cuemaker to shit the bed and piss people off. Also the government is giving tax breaks on bullion buys, they aren't doing the same thing for cues.

As far as assessing value based on how a cue looks, simplifies it for you, but the reality is the brand matters. Two watches do the same thing but a Timex is still a far cry from a Rolex. Personally, I use my Iphone, but occasionally I might throw a watch on. It is a cheap watch, but it is sentimental.
Collectors have to love collecting, that has to be first and foremost. If you are lucky enough to collect the real high-end cues, maybe there are 6-12 makers that constantly stay strong, then you can be "both" and at the end, be lucky to escape with some extra. Make smart choices, I always will reference my friend who asked my opinion on two 2500-dollar cues. I recommended one, he went the other way because it was fancier.. well that did not work out for him. He chose a McDaniel ivory dagger cue, over Barry Szamboti's 200th cue which was a plain titlist. You do not need to be a rocket scientist to know which one today has a better cash out value.
I fell in love for old paper money, primarily for the historical relevance. But the values are based on a real grading scale that is generally accepted throughout the market. The value of a restored bill will never be that of an original uncirculated bill. This is a major aspect I find missing in cues and always have.
