There is no bonding jumper wire required on a 200 amp service panel. The meter stack is metallic and is continuous from the mast head down to the distribution panel.
If you are talking about the ground wire for a 200 amp panel it requires a #6 bare copper conductor that connects the grounding rod or plate to the neutral point in the distribution panel.
Assuming the answer above is an example of a service, where the meter is stacked above the first service disconnect and is mated to this panel by a threaded hub. However if your meter were to be mounted beside your first service disconnect and a metal nipple with lock nuts were used for raceway. You would be required to have a bonding jumper on that nipple sized according to NEC Table 250.122. So for 200 amp that would be #6 copper or #4 aluminum.
You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.

If what you state in this question is accurate this is an illegal installation. A 100 amp service can not have any equipment connected to it less that that of the service size. The 60 amp main panel must be a 100 amp panel to be a legal installation.
A 200 amp service panel will require a # 4 bare copper ground wire.
If it was preinstalled, it may have been adequate at the time of installation. It depends on the power requirements of the home. If this is a new install, the NEC has a minimum of 100A for service equipment. To be honest, I would install 200A minimum to allow for future expansion.
Based on NEC 250.66- #2 copper or 1/0 aluminum.

In comparison to its size, the horse is not the highest jumper in the world. Proportionally, it is the grasshopper.
The animal that is the best jumper and not relative to body size is the flea. However, the kangaroo is also known for its jumping abilities.

It was probably a 150 amp service back in 1995. Todays services are usually 200 amps.
