You should be okay with something as recent as MP Grimlock.
The asian clothes shop on chapel street had the masterpiece prime mould in a knock off version. It looked really cheap and was $20. They also had the dvd edition hasbro prime as a display. It was faded pretty bad and I thought it would make good custom fodder... asked the guy for a price and he said $170, $180... I didn't buy it!
Crap...that's where I bought my Masterpiece Prime from (assuming we're talking about the same clothing shop).
But still...
Crap.
Well...my Prime looked pretty legit to me...although I only just recently got into the whole masterpiece thing around May this year so I'm not all that familiar yet. Oh well...he'd better be legit, considering what I paid for it...![]()
You might want to consider taking a photo of yours (toy + packaging if you still have it), and post the pic up using a free picture hosting site such as photobucket so we can all have a look for you.
I was quite surprised myself to discover that there are KO MP's floating around - saw an Optimus one for sale at the markets over the weekend with an asking price of $80!![]()
