Price check on Crystal Lugia

Purchased a NM Crystal Lugia for $100 about two weeks ago, but saw today that a NM/M one had sold for $290+. Wasn’t sure if I happened to nab one at the right time or was this more likely shilling?
Thanks in advance

Should add that both were raw, ungraded cards.

290 isn’t a realistic price for raw NM

Yeah I didn’t know if I was missing something or what… Here’s the link

The seller has some other crystal cards that just went at auction for what I would consider somewhat reasonable prices… possibly a little high, but not astronomically so.
NM/M Crystal Nidoking- $69
NM/M Crystal Golem- $76

From the beginning of the auction it was basically 1 guy with low feedback who started the bidding at $85 and just him bidding up until about $230… Seems like shill imo

A few weeks ago a couple of raw 1st Ed Blaine’s Zards went for $230+ and $300+ with the same bidder winning. The $230 one was relisted and sold for $102. I expect a similar outcome for this.
