Putting a value on a lens

I have a Canon 100mm macro lens, which is neither the L version, nor the recent USM version, but an even older one.





According to the Canon camera museum it is this lens:

I however have trouble putting an exact value on the lens. I'm not even sure whether it was a common lens or whether it has some vintage value or not. It is quite hard to find listings on Ebay for this lens one of the very few I found was this one for around 310 euros: http://www.ebay.com/itm/Canon-Makro-Macro-Objektiv-EF-100-mm-1-2-8-/300594694016?pt=DE_Foto_Camcorder_Objektive&ha sh=item45fcd70780





Then again there is another listing where it did not sell for the equivalent of 250 euros: http://www.ebay.com/itm/Canon-EF-100mm-f-2-8-Macro-w-caps-EXC-/270814628530?pt=Camera_Lenses&hash=item3f0dcf4 ab2





Has anyone had any experience with the price of this lens, or has some idea of how much it is worth?





Thanks!

Ooh that

You can also check the Buy & Sell section of fredmiranda.com. I see there are a couple of 100mm f/2.8 non-USM lenses that sold, one listed for US$360 , the other in bargain condition for US$250.

It was released in 1990 and discontinued in 2000. Vintage? If so, then I'm really, really old...
