Antique bill spikes or receipt holders... used on desks in general stores or offices to hold receipts or important papers. I don't know what got me started on these... there's something about them that I love. Someone had given me one and then I was hooked. Once I have 10 of something then the collection has officially begun! I find the cast iron or metal bases of these interesting pieces really beautiful. I love the way they look in a group and the fact that not everyone knows what they are when they see my collection. Makes for an interesting conversation I guess!
