As a good rule of thumb, I don't really care for anything that:
1. Has a grossly oversized label. What in the hell is this? It looks so tacky!
2. Is hot stamped. When I first learned to play, the first set I used were these turkeys and they looked kinda tacky. I should be thankful that this brought me into chip collecting in the first place, but honestly... I don't care for them:
3. Pretty much anything in the dice chip quality category, including the 13-14g chips each. I figure if you don't know what those are, you're probably in the wrong place.
4. Anything that's cheaply made or can be knocked off too easily, case in point the Scroll ceramics or this:
This was actually my mom's first love as far as a chip set is concerned but then I saw how prone they were to breaking and I went "hold up". I don't collect a lot of China Clays because most of them don't look as customizable as I'd like but even by this standard, I didn't care for it.
5. Anything that's too traditional a design. Take a look at this:
The quarter chip is actually nice looking, but the rest of these I could take or leave unless I re-labeled the shit out of them. The font looks too much like someone wrote it with a typewriter and the first time I saw these chips, I had to go on my laptop to verify it wasn't a turd in the pot, when the color is that dark brown, that's what it looked like. I literally went "no one would make that". I showed this chip to one of my friends and she said it looked like it came out of the '70s. Maybe the $1 was just poorly made compared to the others in the collection in this picture but the edge-spot alignment is an eyesore for me at least in that picture. The rest of them are okay, but I really don't get the appeal.
6. I hate to crap on Gene's work (I think the guy's a genius) but this is one of the worst chip designs I've ever seen:
why? It almost looks like someone's making a meme when you put the dollar amount in the chip. There's nothing wrong inherently with the design but the numbers kill it for me. The numbers should have been better integrated into the chip, if you look at my current favorite from Gene, the DDLM, you'll see that it does fit. You can make that amount any amount you want, and it will still look like it belongs on the chip.
