There are a number of web sites you can use to get valuations. For LPs Audiophileusa.com has listings in all categories. For jazz Gsjazz has lot of listings especially older LPs. Both EBay and Amazon.com are good sources I have found many items in my collection listed there for sale.
Discogs is another good source. I buy a lot on there and a lot of items have multiple listings including condition and you can determine an average current price.
