Help with info, please

Hey gang, can anyone help me?
I'm working on an estate sale for a friend and can't find out the year of introduction and catalog retail price for a G scale set #90022 "Gold Rush" and an On30 scale set #25001 "Wonderland Express"".

Any help would be greatly appreciated.

I don't  know about dates or catalogs prices but Googling shows people asking between $115 and $182 for the On30 one.
It looks like the Gold Rush is from 1994.

I saw one on Ebay for $160.
Here's one for $100

Thanks, Terry, that helped some.  I appreciate that.
It doesn't matter to me what the prices people are selling for now. (But I do find it interesting)  The people asked me only for the original retail.  They'll be setting the prices

The date for the Gold Rush helps and I guess the Walthers price is probably as close a number as I'll get for retail.

Anyone else out there have more to add?
