I found a #4 today. They wanted $10 for it. They also had two Lodge ashtrays and wanted $9 for each. Not sure why they thought an ashtray was equal in value to a number 4. They came down to $5 on the ashtray, but then didn't have $5 change for my $20 ... so I bought both ashtrays to make it an even $20.
This is actually the first number 4 I have ever come across...
