Valuing old pedals - D*A*M & Antelope FX Morning Dew

[willo]

Hi everyone,

I used to post here a lot around 15 years ago. That feels a long time ago!

I am getting back into playing my guitar but with a child on the way I am looking to simplify what I have, in particular around FX and amplifiers. There are three things I have that are relatively less common but I'm not sure if that makes them valuable to others - i.e. in terms of price.

JCM800 2x12 combo from 1980 something
D*A*M Sonic Titan #062, from 2006 - pedal has dings but fully boxed and working order https://www.stompboxes.co.uk/Titan.html
Antelope FX Morning Dew - Mint condition, fully boxed --> this example is not mine https://reverb.com/au/item/3356232-antelope-morning-dew-eq-rare-and-discontinued?locale=en-AU

There's enough of the JCM800s on eBay to work out a reasonable 'market price', but does anyone have any pointers on finding out reasonable values for the Sonic Titan and the Morning Dew? Are these pedals still considered desirable?

Any help much appreciated!

Thanks
Ian
