Yeppers, you are correct; these are very common. You'll see them in many Antique malls for between $1.00 and as high as $5.00. Most places have them either $1.00 or $2.00.

These were from home poker sets. You'll see them in all sorts of motifs; dogs, jockeys, various symbols, etc. I believe they in 4 different colors.

Careful though...they break easily if dropped on a hard surface.
