Should I Hold On To These?

I am not a serious bill collector but I would keep them until you find better ones.

For me, it's just fun to find interesting numbers. I suppose if I ever found a true binary or a radar note I would quickly lose interest in my 'almost fancy' serial numbers.

Thanks for the replies everyone!

ckrakowski, I'm probably going to hold onto all of them at least for now. That 01018585 is a pretty neat find that I almost missed. I typically only look for stars and colors other than green when searching, but that one was so unique it actually stuck out to me.

Buddy, I hear ya! I had found another note with all but two of the numbers being 7 and I find it less interesting now that I have found this 01018585 so it may find itself being spent. I would be more inclined to hold onto it if it were crisp but it is not.

BLadd, that is exactly what I found today. Mine has some pretty obvious marks in fields but the device is still in good shape and has some really nice luster. I noticed these do not have dates on them. Why is that?
