Sale prices on eBay have been analysed to evaluate West German Pottery price trends. The aim is to monitor the changing value of Fat Lava pottery through analysis of UK eBay sales. The intention is that this will provide a barometer for the popularity/desirability of Fat Lava items.

The average sale price (plus postage) of West German pottery items during April 2013 was £22.79 down very slightly from the previous month (£23.13).

The top 20% most expensive Fat Lava items average sale price (plus postage) has surged to £149.37, the highest level recorded since analysis started 20 months earlier. This major increase in recorded values can be partly attributed to the high quality of fat lava items sold during April, including a number of sought after Roth, Ruscha and Otto items.
