Total Linsanity has hit the NBA, and now it is trickling down to the card collecting world.

I mean, this is bigger than Tebowmania, as blasphemous as that may sound.

New York Knicks sensation Jeremy Lin proved Friday night he was more than a flash in the pan, scoring a career-high 38 points to help his team defeat the Los Angeles Lakers 92-85.

His average over his first four NBA starts with minutes is 28.5 points and eight assists per game. And although he only scored 20 points Saturday night, his free throw with four seconds left gave the Knicks the lead for good in New York’s 100-98 win against the Timberwolves.

Not bad for an undrafted point guard out of Harvard, the first Ivy Leaguer to play in the NBA since Yale’s Chris Dudley debuted in 1987 with the Cleveland Cavaliers. And Lin had the numbers at Harvard, as he was the first Ivy League player to score 1,450 points, grab 450 rebounds and get 200 steals during his college career.

Needless to say, Lin’s rookie cards (he was with Golden State last season and was picked up by the Knicks on Dec. 28, 2011) have rocketed in value this week.

Panini America reported on its blog that in the last 24 hours, some of Lin’s autographed rookie cards have sold for up to $1,000. Another one also sold for $799, and others are fetching $200. Even non-autographed cards are being snapped up at auction for $100.

And how weird is this?

On eBay, there is a 1/1 Lin rookie card, a National Treasures autographed card with a game used swatch, graded 9.5 by Beckett. There’s a Buy It Now for a mere $100,000 (money order or cashier’s check, of course). There are six days remaining if you are trying to rustle up the funds.

That’s not Linsanity. That’s just crazy.

Especially when you realize that Lin’s highest-selling rookie card went for $40, and many could be had for $3. On Feb. 3, a similar card to the one that has a $100,000 price tag (I am still smirking at that one), sold for $21.71 on eBay.

Auction sellers on eBay, recognizing a hot trend, are putting that particular National Treasures card (numbered to 99 with auto and swatch) online for one day. Two of those cards have bids of more than $1,000.

As long as Lin keeps playing to a high level, his cards will sell for inflated amounts. Playing in New York will keep his profile high, and as the first American of Taiwanese descent, he has international appeal.

And if Lin keeps scoring, his card values might stay high, too. Perhaps that guy with the $100,000 Buy It Now tag will push it up to $200,000.

At either price, that just won’t fly.
