Only 25 percent of gold was turned in during 1933 during the gold ban here in America. Most people kept what they had which most families didnt own gold anyway, but you were allowed to keep a few ounces. The government only wanted it back before they revalued it. They had no way of knowing who had what and no one went to jail. Gold was still traded like always and nothing changed. I have some coins from that time period that survived and theres alot out there that did. Nowadays they dont need the gold. They can push a button and bail in the banks. Thats why every country enslaved to the central bankers have passed bail in laws. Not because they are stupid.
I reckon a $200 denominated gold coin has a scarcity value given it has a known mint quantity for that year along with a numismatic value on top of its gold value A Blob has neither so I'd opt for the 1 Oz coin version
A lot depends on where you plan to sell if you need to, a place here like silverstakers will see you get a better return for a coin specially if its rare, low mintage, hard to get etc etc. However if you plan to sell to a dealer 1oz is 1oz no matter what it is. Personally I like generic blobs they are nice to hold. If your budget allows get a bit of everything and have all bases covered, gold is good in any form!!!
Much easier to hide 1oz of Gold than 100oz of Silver. If either metal becomes monetary again you can rest assured it will happen to both. Unimetallism doesn’t last for long before arbitrage in overseas markets wipes the economy out (can study the history of Venetian states for evidence).
Only an estimated 25% of gold was turned in during the 1933 mandatory turn in in the US. Lots of it out there still today.
