Am I sitting on a goldmine?

[vsp]

I have a Mac IIfx sitting across from me in my computer room. It has the staggering total of 128MB of RAM in it -- pretty damn spiffy in 1990 terms. (It started life as a main server for a former employer's flagship application; by the end of the decade, I actually got it for free because they were going to throw it out.)

While looking something up recently, I decided to see how little the RAM went for these days. The RAM is proprietary -- there's a LaserWriter that it's compatible with, but that's it, as it was the only Mac II that used 64-pin SIMMs.

I found exactly one place with it in stock -- and they wanted THREE HUNDRED BUCKS for FOUR 16-meg IIfx SIMMs. I have eight.

Just to make sure that I wasn't seeing things, I did some more digging. One said "Back Order" for four 16-meg IIfx SIMMs at $217.

Is there any recommended Apple guru out there that can verify whether these go for anywhere near those figures? (It would go nicely towards a new computer, and given how old this Mac is and what I paid for it, I'm not above cannibalizing it.)
