2000 Off-Center ANA First Steam Press Medal Value Request

I got this medal a few months ago. I was wondering what the value is. Here's some info I found about this medal:
The diameter of this medal is 27mm, and a total of 2,220 of these medals were minted. 2,000 in .995 copper, 200 in .999 silver, and 20 in 22kt gold. This was originally supposed to be struck at the Franklin Institute Science Museum in Philadelphia, Pennsylvania on March 23, 2000; due to mechanical problems however, the date was postponed and struck at the Gallery Mint Museum in Eureka Springs, Arkansas instead. After they finished striking these medals, the steam press was donated to the ANA and is on display at the Money Museum in Colorado Springs, CO.

I see two sold listings for non-error versions of this medal on ebay. They each sold for about $10. These were sold on March 24, and March 31. There are also 2 unsold listings. One for $35, and another one trying to sell the copper and silver version for $95. I also know a die pair that struck this medal sold for $705 in a stack's bowers auction.

How I got this medal:
The ANA has a monthly YN (young numismatist) auction; having three or four lots you can choose to bid on. In the auction, you're only allowed spend ANA currency called YN dollars. You can get YN dollars for completing certain activities. This lot sold for 242 YN, and was the most popular lot with over 20 bids.

Are there any other known errors? This is one of my favorite pieces in my collection and I don't plan to sell this medal. Value and possible new info would be greatly appreciated. Thank you!
