Thanks for your reply.
In case there is a misunderstanding, this wasn't an RID toy (if you are referring to RID Megatron), it was a Botcon toy representing G1 Deathsaurus from Victory, however it was originally an RID mold.
If it is indeed Botcon Deathsaurus, I am not sure how much he is worth but this fairly recent TFW2005 price check has it at $200 for the 5 piece box set and $65 for Deathsaurus alone.
I was actually looking at something like that as last time I saw it on Ebay it went for something like $70.
