All that can be told from the photos is the following:
The PCB is an Acclaim board using the Acclaim MC-ACC mapper/chip (similar to Nintendo's MMC3).
The board is wired for 27C101 EPROMs, two of which are present; the EPROMs (each) are 128KBytes (1mbit) in size. What they contain is anyone's guess (you say Mickey's Safari in Letterland, but whether or not it's a "real" prototype is unknown).
I don't think anyone's going to be able to tell you what you should sell this for (price-wise) because nobody here knows what's on it, knows if the code is different than existing ROM dumps already out there (and if so what the differences are), and so on.
*I* would like to know how you determine this was a prototype -- there is nothing in the pictures you've provided so far that indicates such.
As for people wanting to buy it immediately off eBay -- not surprising. I wouldn't be surprised if they did this due to cart rarity (in general), with the sole intention of putting it back up for sale for a higher price than what you had asked for. This is incredibly common on eBay, especially with "rare" or prototype carts -- again, if it even is a prototype cart... :-)

Acclaim used that same PCB in various commercial releases: http://bootgod.dyndns.org:7777/search.php?pcb=53361-2
Re: Prototype NES game - Mickeys Safari in letterland HELP
Unless anyone modified it, there is a good indicator that it's not a production copy: the EPROMs are in sockets, and are in a ceramic package. Date code on the EPROMs is late 1990, which is the right time period. The EPROMs look like they've been erased and re-labeled (traces of the old adhesive), but that's not too surprising. To see what's on it you need an EPROM programmer to read the chips (or an NES cart copier, like CopyNES). I'd guess it's most likely going to be the same as the release copy, but that's pure speculation. It's probably safe to say it's worth more if it's different or has some sort of known history. For a value, you might be better off asking on NintendoAge where there are collectors of this kind of stuff.

Although I'd like to note that just because there's indicators that this could be a proto...Eproms do not neccesairly mean it was not a production cart.
A dump would really clear a lot up.
edit: Of course the sockets are suspicious for any production cart.
edit2: On that note, how in hell's name does that cart close with the sockets? Are they super low profile or something?

Being a development cart still doesn't mean it's a prototype, it could be just a preview build (for sending to magazines, etc.).
