Question about Double Mint Sets

REALGATOR

Did all of the mailing envelopes from 1948 have a Treasury Department stamp on them? Is the set more valuable with the stamp and original receipt?

I would go back to the old saying

BUY THE COIN NOT THE HOLDER!

Isn't that a 1949?

Some people pay a premium for still sealed sets. Others won't touch them.

REALGATOR

It is postmarked 1949 and its not sealed. Actually the front of the envelope is torn, but everything else is ok. The coins have the typical mint set toning. I just don't ever remember seeing the Treasury stamp, but I haven't seen all that many of these.

I don't know if they all have it, but it is not unusual. I've seen them before.

No. The set inside would be a year before the stamp. That was how it was done back then. Order but not receive for quite awhile.

Same with the later dates of double mint sets (I'm not sure when it stopped) as the ones from the mid/late 50s follow that pattern as well (I currently have probably a dozen or a little more of the 1955-1958 sets and they all have followed that pattern)

Yes the set is 1948 but the postmark is 1949. Not much has changed in 70 years! Still its the only one I've seen with a Treasury stamp on the envelope. But I have only seen a few.

There are "outside set" envelopes and "inside set" mint set envelopes. When the original purchaser ordered just one set, you received it in an envelope with the address and postage stamps on the outside. When one ordered multiple sets, there was the outside envelope and blank envelopes that contained the individual sets on the inside. I find these sets to be less interesting, but I have no idea if they are worth less money that the outside envelopes. I know from my limited experience in this area, it doesn’t seem to make a difference.

When I was dealer I bought a group of five mint sets that were sealed with outside envelope. The dealer from whom I bought them assumed that they were 1955 sets given the postmark. I went to see a dealer friend who was an expert in modern coins. He told me right off the bat that the sets were probably 1954s. The reason was that the post mark was for early 1955, and he knew from experience that some mint sets from the previous year were mailed the following year. Sure enough, when we cracked them out, they were 1954 sets and were worth more than the 1955 coins.

As to the treasury seal on the back of some envelopes, I can’t answer your question. I don’t know what the policies were, but I don’t think that they add to the value of the set. I think that the situation was similar to the inside and outside envelope question.

Thanks everyone for the info. I'll take some photos of the set and put it up for sale.

That's not what I was referring to. The OP asked if all 1948 envelopes had seals. Regardless of contents that's a 1949 envelope.
