  • A couple 10oz Griffins proofs arrived. The premium was insane but I have a good feeling about these rising being limited to only 140pcs. After premiums on ASEs shot up, I’ve been buying more semi numismatic items. What do you guys think about this expensive bet?
    Nice catch, I like the Griffin most in this series but I only bought the 2oz bu ones. It is a hot series, so I would say it will not be too hard to sell the 10 ounce proofs. Maybe try https://ma-shops.de or catawiki.com if ebay doesn't... Source: over 5 years ago
