Over the course of my silver and gold bug evolution I have done similar things. In my experience, it has been more of a waste than a gain. If you like something and want to collect it then it's fine. But I found what works best for me is buying what I know I can sell at a profit right now instead of trying to guess what will be popular later or simply buying a bunch of stuff that seems "cool" to me at the moment.
I started out buying circulated US silver dollars (worst investment ever since very high premiums) thinking I was buying bullion. Then moved to Engelhards (that was good since they were cheap back then), then went to generic 1 and 10 oz bars, then gov minted coins, then foreign silver I get cheap (best deal for me) and then to US gov issued coins in fancy boxes or cases- commems and older silver proof sets, etc. that I can get cheap.
Now when I go out searching for things to buy I know what I can flip if necessary or what is selling for much more on ebay and I buy those things, as long as I can get them cheap. Sometimes if I am feeling the buying addiction and nothing on my "list" is available I will get cheap silver bars if they are available, just to keep the addiction at bay for a bit.
I found that the stuff I switched to that I thought was cool, would later become boring and I would switch to something else, on and on. Nowadays I won't buy stuff that isn't on my "list" for the most part, unless I plan on stashing it for a long time.
Just my opinion.
