It is unknown how many were originally made, but in the manga all bar Kon were said to have been destroyed. In the anime, however, there are three from the Bount arc ( Ririn, Noba, Kurodo) and many more in the Gotei 13 Invading Army arc (Kageroza Inaba, Nozomi Kujo, Oko Yushima and all the Reigai characters).
