Weird day...thanks Tony, pity about the Vaal, but always good to hunt with you. Not every day you find 176 coins...

Brendan, here's a summary:
New 5c 60 (1990 to 2006)
Old 5c 1 (1979)
Old 2c 7 (1977-1989)
Old 1c 13 (1970-1989)
New 1c 54 (1991-2001)
New 2c 39
New R2 1
New 20c 1
Although definitely not old, I quite like the old 2c and 1c pieces. Like chalk and cheese when compared with the new 5c, where even a 2006 coin is pitted.
Think someone lost a piggybank in the veld?
