I started collecting elements on the periodic table a few years ago, and here is a list of all the elements that I have pure samples of so far.
A few of my favorite samples include my 1g of cesium metal. It is in an argon-filled glass ampoule with super shiny, 99.99% pure cesium metal, and it is the color of 14 karat gold! What's better is that it has a melting point of 83.19°F (28.44°C), which means it will melt in your hand when held for only a few seconds! Considering it's high reactivity, it really makes me wonder how they got it so shiny. Best $100 I ever spent!
Another favorite sample is my 864g (1.9lb) tungsten rod, as it is incredibly heavy with a density of approximately 19g/cm³, nearly 2½ that of steel! It is a really unusual feeling to pick something like this up.
My all-time favorite element is gallium, because it will melt in your hand just like cesium, except without burning a hole through your hand. I even sell gallium over the Internet. I have bought 2kg of it.
I have a list of the 28 elements I have collected so far, with a link to a picture for most of them.
